Caute borci,

I have a following issue on Debian stable using libzmq 2.1.10-1 compiled from unstable, so I am not sure if it goes on account of Ruby bindings or zmq library itself. ruby-1.9.2-p290 hangs when running an example from README.rdoc. Here is a stack of all threads.

Sry, my bad. It's ok.
