For sure. I'm not a fan of sending messages to threads to shut them
down. The ZMQ_TERM semantics are a big help in killing a MT
application cleanly. This has to be properly explained in the Guide
and probably also in the man pages.

But we also sometimes use threads as process simulations, and they do
not then share contexts, and cannot be shut down like this. And often
we're using SIGINT, which has to be handled explicitly by a signal
handler.
