Summary:                    iax2 deadlock asterisk
Description: 
I have upgraded two servers conected via iax to asterisk 1.4.21-rc1 and
after some hours, asterisk deadlocked and the CPU usage jumped high in
both. This problem appeared many times in office hours and i reverted
immediately to 1.20.1 because there are productions environvment. So i
don't have any informations. But i'll try to reproduce the bug in test
enviroment so i'll post the necessary info later. Only to advice that
something is wrong in chan_iax2 with the lastest changes from Russel.

Just to be clear, rangib's upload of 'core show locks' was what enabled me
to find and fix this issue so quickly.
