To quote the document leaked from MS last year on Linux:

There are literally hundreds of small research projects attempting to
improve various parts of the Linux OS.
Some projects include:

* Linux 2.2 - High Availability features such as deeper RAID support
(RAID 0, 1, 5 supported today), volume management; file system
performance improvements; asynchronous I/O & completion ports;
Ipv6; . An excellent feature summary can be found on:
http://lwn.net/980730/a/2.2chFinal.html.

Seems we already have completion ports ;)

If I recall they were added late in the 2.1.x development cycle, you wasted
a full head of steam and a batch of flames for nothing I'm afraid.
