Summary:                    [patch] safe_asterisk can get multiple instances if
killproc escalates to SIGKILL in service asterisk restart
Description: 
Weird behaviour was observed in which we got Remote UNIX connection and
disconnections continuously repeated.  It turned out that we had two copies
of safe_asterisk running.

Although I didn't do this myself, I believe this was the result of using
"service asterisk restart" on an asterisk that was in distress (deadlock,
at least).  I think what happened is that the killproc escalated to
SIGKILL, which was not recognized by the original safe_asterisk, so it
continued to run.  Meanwhile the new safe_asterisk was started, but both
checks for a running asterisk failed, either because it was too much in
distress, or because the console listener had shut down in response to
killproc's SIGTERM.
