Ok, I've checked it in.

BTW, what are your plans regarding the boehm-gc  integration? I've
stumbled across a function pointer called GC_push_other_roots which
can be used by the application to push root references the gc can't
know about. So it looks like we could use it to traverse the list of
running threads using jthread_walkLiveThreads, just like kaffe-gc
does. This in turn would mean that we could make boehm-gc use the
jthread layer (provided that we find a way to trick boehm-gc into
using jthread_suspendall). Have you had a look at this possibility?
