[Bug nptl/415] pthread_cancel does not unwind stack when thread is cancelled inside signal handler

Dear Ulrich,

I want to make one correction: I tried call pthread_exit from the signal 
handler and it works, thread stack unwinds and local objects get destructed, 
that's good news.

Now the question is that since the standard says all Pthread functions are not 
safe to be used inside signal handler, how safe it is in reality to use 
pthread_exit inside signal handler on Linux using NPTL?

Thanks very much.

Yufeng
