What does mark conversatively mean? NSPR doesn't have a way to access the stack objects of each thread, so I'm in a bit of a bind. The NSPR threading library does have pretty much everything else a threading library needs, and is very clean.
Marking conservatively means marking every object that is pointed to by any value on the stack (or in registers). What "conservative" refers to here is that a value on the stack might look like a pointer, but actually be a value of another type that just happens to look like a pointer, or even uninitialized data. Thus an object that's actually garbage might not get collected, hence the collector is "conservative" in keeping it alive. You'll need a threading library that does give a way to find the stack of each thread, so you may not be able to use NSPR. -- Darin
