Kevent based AIO (aio_sendfile()).
aio_sendfile() contains of two major parts: AIO state machine and page
processing code. The former is just a small subsystem, which allows to
queue callback for theirs invocation in process' context on behalf of
pool of kernel threads. It allows to queue cach
Generic event handling mechanism.
Kevent is a generic subsytem which allows to handle event notifications.
It supports both level and edge triggered events. It is similar to
poll/epoll in some cases, but it is more scalable, it is faster and
allows to work with essentially eny kind of events.

Private userspace notifications.
Allows to register notifications of any private userspace
events over kevent. Events can be marked as readt using
kevent_ctl(KEVENT_READY) command.

poll/select() notifications.
This patch includes generic poll/select notifications.
kevent_poll works simialr to epoll and has the same issues (callback
is invoked not from internal state machine of the caller, but through
process awake, a lot of allocations and so on).

Timer notifications.
Timer notifications can be used for fine grained per-process time
management, since interval timers are very inconvenient to use,
and they are limited.
This subsystem uses high-resolution timers.
id.raw[0] is used as number of seconds
id.raw[1] is used as number of nanosec
Socket notifications.
This patch includes socket send/recv/accept notifications.
Using trivial web server based on kevent and this features
instead of epoll it's performance increased more than noticebly.
More details about various benchmarks and server itself
(evserver_kevent.c) can be found on
Kevent posix timer notifications.
Simple extensions to POSIX timers which allows
to deliver notification of the timer expiration
through kevent queue.
Example application posix_timer.c can be found
in archive on project homepage.

Signal notifications.
This type of notifications allows to deliver signals through kevent queue.
One can find example application signal.c on project homepage.
If KEVENT_SIGNAL_NOMASK bit is set in raw_u64 id then signal will be
delivered only through queue, otherwise both delivery types are use
