Hi,

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=182116

Steps to Reproduce:
1.Start print-threads within GDB
2.Set a breakpoint in __pthread_unwind
3.Run the program
4.When the program stops at the breakpoint, run `info threads'


Patch disables handling of the TD_DEATH notification from __nptl_death_event()
and tries to keep the thread in TD_THR_ZOMBIE state as long as possible before
its LWP ceases to be. While expecting regressions so far no such was found,
statistically it improves some testcases (+24 passes,-14 fails), no negatives.
('longjmp' part not resolved; not reproducible for GDB-CVS)

Thread is now debuggable through pthread_exit(3) and the thread terminating
code.



Regards,
Jan Kratochvil
