[zeromq-dev] Erlang Ports and zmq_poll

[Serge Aleynikov]

Thanks Chris for submitting the patch.  I was somewhat reluctant to 
porting implementation to 0MQ 2.0.7 as I was waiting for some update on 
Martin's work on making 0MQ sockets transferable between application 
threads.  However since you've done the porting work, I'll test the 
patch tomorrow and apply it to the master branch if there are no issues.
