Not sure what use it would have.

Yeah, managing those is not really recommended manually, and this is
doublessly more interesting, but libeio uses so many system functions that
I doubt it is as useful as with libev.

I would say it would be more useful to, say, have a freelist to avoid the
calloc per request etc.

Personally, I would see an extra set of wrappers as much more confusing
than helpful, not to mention the maintainance effort.

Also, does "managing your memory yourself" include paths (libeio currently
does strdup)?
