WIP: Socket migration between threads, new zmq_close() semantics
Sockets may now be migrated between OS threads; sockets may not be used by more than one thread at any time. To migrate a socket to another thread the caller must ensure that a full memory barrier is called before using the socket from the target thread. The new zmq_close() semantics implement the behaviour discussed at: http://lists.zeromq.org/pipermail/zeromq-dev/2010-July/004244.html Specifically, zmq_close() is now deterministic and while it still returns immediately, it does not discard any data that may still be queued for sending. Further, zmq_term() will now block until all outstanding data has been sent. TODO: Many bugs have been introduced, needs testing. Further, SO_LINGER or an equivalent mechanism (possibly a configurable timeout to zmq_term()) needs to be implemented.
