Re: [rvm-research] Interrupting JikesRVM thread periodically

Yes, the opt compiler uses this kind of mechanism to do some of its 
sampling.  Look at RVMThread#yieldpoint(...) and TimerThread.

It's complicated, and I haven't used it myself.  The complication is 
that Java threads must only be interrupted at GC safe points, so any 
timer interrupt needs to tell the thread to take the next yieldpoint, 
and wait for the thread to arrive at the yieldpoint.

You should also look at the org.jikesrvm.adaptive.measurements package 
and see how the AOS system does this kind of thing.

cheers
