Summary:                    Crash in chanspy
Description: 
I've tested 1.4.18 rc2 with automated call-center tests, and got crashes in
app_chanspy for several times (after 1 hour of running).

Attached full backtraces for two crashes (rc1 and rc2) and valgrind logs
for rc2 running for 10 hours (without crash).

I tested with 1.4.18 rc3 and chanspy.diff2 applied. 

First i got deadlock of SIP (IAX seemed to respond to IAXmodem
registrations) - registrations and incoming calls timed out, "show queues"
and "show channels" exited immediately. I killed asterisk with -5 and took
full backtraces. See attachments 2008-01-31-a-*

After that i enabled DETECT_DEADLOCKS in menuselect, and got two segfaults
(attachments 2008-01-31-b-* and 2008-01-31-c-*) on
