Summary:                    sending a large number of calls to app_meetme causes
kernel panic
Description: 
On machine 1 create a dial file that calls machine 2 plays about 30 seconds
of test messages and hangup.  Create one of these every 5 seconds.  On
machine 2 put all incoming calls into a meetme conference.  After a couple
of hundred calls machine 2 kernel panics.  I have dialed in using SIP and
on the PRI.

Ensure the channel is in a good state before placing it on the chans
arrays.
Also ensure that dahdi_receive holds the chan_lock while iterating over
the
chans array to prevent channels from entering or leaving the array while
the
interrupt handler is running.
