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.
