Summary:                    [patch] Deadlock between dahdi_exception and
dahdi_indicate
Description: 
I've encountered a deadlock situation between dahdi_exception and
dahdi_indicate, running Asterisk 1.6.1.6 (confirmed as well in 1.6.1.14) on
Debian Lenny x86_64.  Deadlock occurs roughly once a week, usually under
lower call volume (strangely enough).  The issue seems to arise mostly when
swapping between call-waiting lines on a DAHDI channel.
