[sr-dev] Crash bug

[Alex Balashov]

Unfortunately, we do keep running into total deadlocks with this 
approach under high load. We've had to revert async call processing 
(with mqueue + rtimer + t_suspend) back to non-async because the 
deadlocks were growing politically unacceptable.

I never managed to get a backtrace of the state of the processes at the 
time the deadlock occurs, because the customer would soon restart the 
proxy when this happened, as it would happen during busy times in the 
middle of production days. The only core dumps I have are the crashes on 
shutdown, which strikes me as incidental/irrelevant.
