Re: Traversing the stack frame and identifying "references"

Thanks for the link. It was very useful. I have one more question though. In 
order to suspend all the threads, the GC needs to have information about all 
the other threads created, e.g. handle to threads etc. In controlled 
environments like JVM, its ok, as each newly created thread can be recorded 
with GC. But how can it be done when the garbage collector is written for 
languages like C++. Do we need to somehow ask the compiler to do that? Or 
some other techniques are used?

Thanks,
Unmesh
