Title: add threadsafe switch to ZMQStream

wraps any calls to io_loop API in add_callback, which is the only thread safe
method on the IOLoop object. This can introduce delays in the events for
code under heavy load, but they should have minimal effect, as the same
delays would affect the handling of the events in the same way they affect
the registration thereof.

Off by default, so existing code will see no changes.
