Yes, having separate implementations of the transport layer should work.
But I think it would be cleaner to put all the platform specific stuff
in the pollster, and make the pollster poll-for-completion rather than
poll-for-readiness. (Is this the "proactor pattern"?) That seems to be
the direction libevent has moved in.
