--- Comment #7 from Sledge Ham <mahegdels at telenet.be>  2009-09-24 06:56:06 MDT ---
If I compile with DEBUG_THREADS it looks like some foreign threads are being
created and being allocated in the GC_threads-array.
However, when the garbage collector runs, this thread is already gone again and
when we perform the thread_get_state() in darwin_stop_world() this returns an
error.

To be sure that the filters from thread_get_state() are not incorrect I added a
thread_info call right before the thread_get_state and in the
GC_start_routine_head. 
The GC_start_routine_head returns a success... The call right before
thread_get_state fails... 

It seems like the thread already went away... 

Was the mach_thread-properly 'retained'?
