[zeromq-dev] Router/Dealer configuration monopolizes CPU while idle

[Michel Pelletier]

I just did a brief scan of your code, but it looks like your controller is
using poll(0) in two places in a loop.  poll(0) will return immediately and
your code will busy loop around the 'while True' if idle.  I think a better
approach would be to register the router socket with the poller and use
poll(None) always processing the router socket messages first.
