well.. I know about some problem with pthread async thread cancelation. I think
its related to the jdk brokeness with linux2.6. I hope to finish all my SoC
duties "soon" and spend the rest of the SoC time hunting down bugs like this.

if anyone want help:
   www.vlakno.cz/~rdivacky/pthread.c

this program does crashdumps with 2.6 emulation. I'd be very glad if someone can help
me with this. I slightly investigated this and it crashdumps on signal delivery (pthread_cancel
is actually a signal delivery) so I guess something with stack or so is wrong...

havent had the time to investigate further

help is welcome!
