[zeromq-dev] "inproc" socket connection fails onCentos5/AmazonEC

[Dmitri Toubelis]

Sorry guys it's my own fault. There is an oversight in my code - I bind()
and connect() sockets sequentially but in separate threads, so it is not
exactly a sequential execution. Thanks to everybody who responded. Sorry for
the false alarm.
