We do have some limited profiling support.  The "-M" option to ilrun will 
print out a trace at the end of execution listing the number of times each 
method was called.  This can help identify hot spots, but won't show you how 
long they took to execute.

The general approach is to modify the engine to insert special CVM opcodes at 
points where you want to measure something interesting, and collect up the 
statistics that way.
