Summary:                    ConfBridge crashes when leave simultaneously
Description: 
ConfBridge crashes when users leave the conference at the same time (very
timing sensitive).

I have reproduced the issue every time (3-4 times) when using the
res_timing_timerfd timer and with (only tried one time) with
res_timing_pthread timer.

I didn't get the crash when I tried (only one time) with the
res_timing_dahdi timer but I might have just been lucky.

Hi. It has been some time since this crash was reported and I today tried
the latest code from the svn trunk and reproduced the same bug there. I
have attached new log output from asterisk and gdb.

This issue should be changed to reflect that the bug is in the trunk and
not only in the 1.6.2 version. Most probably this applies to the related
issue 0017670 as well.

The bug is easily reproduced on my side by calling simulated phones which
hang up at exactly the same time.
