[asterisk-dev] realtime architecture blocks iax network thread

Thanks - the new multithreaded implementation looks much better - but it 
seems it's still far from stable.
After a few hours on a test server - practically no load, iax simply stopped 
working at the same time 'iax2 show calls' returned nothing while 'iax2 show 
netstats' showed statistics for calls that werent there (not talking about 
the (none) records).

It seems to not hangup iax calls. After placing a few echo calls - and 
hanging up this is what I get:

It does receive hangup though:
