* sendfile replaces read + write
* libeio sendfile replaces
libeio read + libeio write (blocking)
or
libeio read + write (non-blocking)
so if you are replacing a blocking disk-read, then sendfile is
appropriate. if you are replacing an async disk read, libeio sendfile is
appropriate.

I doubt it.

Depends on how you do result processing.

Since you already rely on libeio in your workflow, it is an appropriate lib
for your workflow :) libev probably, too, unless you use another event loop,
or threads/fork, to do your accept thing.
