NSThread limits?

[Marc Wan]

hello!

  I am looking to create a server that maintains a pool of a few
hundred threads at a time, and being a fan of objective-c, i had hoped
to be able to use GNUStep to do this on non-mac platforms.

  unfortunately, I don't seem to be able to fork more than about
150-160 threads using
NSThread::detachNewThreadSelector:toTarget:withObject.  on my macs
here, i can easily do 1000 (i didn't test higher).

  after this on Linux, I get:

: Uncaught exception NSInternalInconsistencyException, reason: Unable
to detach thread (unknown error)


  i had worried that this was a linux (ubuntu 6.10 LTS Server) issue,
but /proc/sys/kernel/thread-max says that it'll handle over 143000
threads ... some casual browsing of NSThread.m didn't immediately show
any limitations.

  any idea why this might be happening?

  thanks,
  mark.
