 @section Subsystem stability
 
-This page documents the current stability of the various GNUnet subsystems.
-Stability here describes the expected degree of compatibility with future
-versions of GNUnet. For each subsystem we distinguish between compatibility on
-the P2P network level (communication protocol between peers), the IPC level
-(communication between the service and the service library) and the API level
-(stability of the API). P2P compatibility is relevant in terms of which
-applications are likely going to be able to communicate with future versions of

 The TESTING library is used for writing testcases which involve starting a

-the ARM subsystem, using TESTING library provides an elegant way to do this.
-The configurations of the peers are auto-generated from a given template to
-have non-conflicting port numbers ensuring that peers' services do not run into
-bind errors. This is achieved by testing ports' availability by binding a
-listening socket to them before allocating them to services in the generated

 @subsection Finer control over peer stop
 
 Using @code{GNUNET_TESTING_peer_stop()} is normally fine for testcases.

-case to send the termination signals to the peers first and then wait on them.
-This is accomplished by the functions @code{GNUNET_TESTING_peer_kill()} which
-sends a termination signal to the peer, and the function
address@hidden()} which waits on the peer.
-
-Further finer control can be achieved by choosing to stop a peer asynchronously
-with the function @code{GNUNET_TESTING_peer_stop_async()}. This function takes
-a callback parameter and a closure for it in addition to the handle to the peer
-to stop. The callback function is called with the given closure when the peer
-is stopped. Using this function eliminates blocking while waiting for the peer

 @node Testbed Barriers
 @subsection Testbed Barriers
 
-The testbed subsystem's barriers API facilitates coordination among the peers
-run by the testbed and the experiment driver. The concept is similar to the
-barrier synchronisation mechanism found in parallel programming or
-multi-threading paradigms - a peer waits at a barrier upon reaching it until
-the barrier is reached by a predefined number of peers. This predefined number
-of peers required to cross a barrier is also called quorum. We say a peer has
-reached a barrier if the peer is waiting for the barrier to be crossed.
-Similarly a barrier is said to be reached if the required quorum of peers reach
-the barrier. A barrier which is reached is deemed as crossed after all the
-peers waiting on it are notified.

 The barriers API provides the following functions:
 @itemize @bullet
address@hidden @address@hidden()}:} function to initialse a
-barrier in the experiment
address@hidden @address@hidden()}:} function to cancel a
-barrier which has been initialised before
address@hidden @address@hidden()}:} function to signal barrier

+barrier service that the caller has reached a barrier and is waiting for
+it to be crossed
address@hidden @address@hidden()}:} function to
+stop waiting for a barrier to be crossed
 @end itemize
 
 
 Among the above functions, the first two, namely
address@hidden()} and @code{GNUNET_TESTBED_barrier_cancel()}
-are used by experiment drivers. All barriers should be initialised by the
-experiment driver by calling @code{GNUNET_TESTBED_barrier_init()}. This
-function takes a name to identify the barrier, the quorum required for the
-barrier to be crossed and a notification callback for notifying the experiment
-driver when the barrier is crossed. @code{GNUNET_TESTBED_barrier_cancel()}
-cancels an initialised barrier and frees the resources allocated for it. This
address@hidden()} and
address@hidden()} are used by experiment drivers. All
+barriers should be initialised by the experiment driver by calling
address@hidden()}. This function takes a name to

+barrier is crossed. @code{GNUNET_TESTBED_barrier_cancel()} cancels an
+initialised barrier and frees the resources allocated for it. This
 function can be called upon a initialised barrier before it is crossed.
 
 The remaining two functions @code{GNUNET_TESTBED_barrier_wait()} and
address@hidden()} are used in the peer's processes.
address@hidden()} connects to the local barrier service
-running on the same host the peer is running on and registers that the caller
-has reached the barrier and is waiting for the barrier to be crossed. Note that
-this function can only be used by peers which are started by testbed as this
-function tries to access the local barrier service which is part of the testbed
-controller service. Calling @code{GNUNET_TESTBED_barrier_wait()} on an
-uninitialised barrier results in failure.
