On some systems, right.

Hmm. Why do you say this? It's true that AIO will require reactor
support (IOCP is essentially such a reactor, except for Windows). I
don't see a problem with using AIO in a single process, though, and
apparently neither did Pavel when he wrote IOCP.

KQueue supports on-disk files, I suspect. There is no working KQueue
reactor, though, so that takes care of BSD/OSX. Windows has IO
Completion Ports, which IOCP uses (hence the name ;).
