I think I've mixed a file descriptor in with sockets once, but not in 
current production code.  A quick thought: you might template the poll 
wrapper so that the user could pass a mix of Socket and int (or whatever 
the proper name is for the file descriptor type per OS).  Inside, you set 
the appropriate property on each zmq_pollitem_t structure based on the 
argument type.

Now that I think of it, you also need to find a scheme for indicating 
which events you want to listen for.  Which means either a simple pairing 
type (socket, event mask) or a getopt-style interface.
