mono_thread_detach () indirectly calls WaitForSingleObjectExt () which
calls GetCurrentThread (), which doesn't find the thread in thread_hash
since it is already removed, so it calls thread_attach (), which allocates
a new handle and puts it into thread_hash. Later, when mono_thread_manage
tries to wait for this thread to die, it waits on the new handle, which of
course is never signalled, so the runtime hangs.

+I think Gonzalo added the mono_thread_detach() calls; I don't think
+they should be there.
+
+(IIRC, it was something to do with threads exiting without unwinding
+back to the start function, and Gonzalo wanting the active threads
+hash table to be updated immediately. I explained at the time that
+the wait_for_tids() function should cope with signalled threads, and
+if it doesn't the bug is there instead...)
