Can you provide a reference?  I could find it myself but I'm too lazy.

Do /dev/poll and FreeBSD's KQ event driven APIs count? IMHO, true async io
as implemented by Windows 4.0 and beyond is pretty slick, but the
programming model is substantially more complex than programming to an event
API like /dev/poll.  And true async does not buy much if the system call
overhead is low (as it is with Linux).
