Would it be possible to add the normal file descriptor into poller_t? It is possible in the c api of zmq so this functionality seems to be missing in cppzmq.

I'm using cppzmq in a multithreaded program which merges measurement data from ADC cards. I have been mostly happy to cppzmq because of RAII. Now, I need to include slow control data into the program via UDP protocol. The sender is not in my hands and is not using zmq so I'm just using posix socket. I also would benefit to have the same poller been able to poll incoming zmq traffic and polling the normal file simultaneously. In meanwhile I have to use the c api for poller.

A side note. Is there any clear reason why the simple zmq::poller_t requires DRAFT api? This makes the installing of my software much more difficult since the installing of DRAFT support is not easy always.
