Ok, my guess is this:

ZeroMQ = BSD sockets + IOCP + High level messaging semantics + BSD socket
interface.

libevent1 = BSD sockets + event loop + evbuffer (application layer mbufs /
SKB) + async DNS
libevent2 = libevent1 + IOCP

GLib = BSD sockets + event loop + IO Channel interface.


Off to research what Google has to say on Linux IOCP.
