[Sablevm-developer] sablevm hang

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Heya,

I'm running into an issue were the sablevm seems to be hanging on what i 
think is a threading related issue. I've narrowed down where in code 
the hang occurs, but i'm not sure _why_ it occurs.  I'm providing the 
class and instantiation along with a portion of strace output.  if more 
strace output would help, please let me know.    

Any help would be greatly appreciated.

System config:
Suse 9.1 updated; x86

Thanks,
Joe
