You should probably just make a ZeroMQ reactor, instead of using TSR,
which (in its current form) is an ugly hack. TSR buys you nothing
because, unfortunately, it doesn't let you hook up to arbitrary

If the API really is select() compatible this presumably would be a
fairly trivial subclass of the reactor in
