New kevent 'take36' release. More interesting descriptions.


Short changelog:

• Fixed typo in Makefile about kevent based replacement for epoll (not included into patchset) which led to compilation failure.
• Changed AIO description text.

 -[take35 10/10] kevent: Kevent based AIO (aio_sendfile()/aio_sendfile_path()).
 +[take36 10/10] kevent: Kevent based generic AIO.

 -Kevent based AIO (aio_sendfile()/aio_sendfile_path()).
 +Kevent based generic AIO.
 +
 +This patch only implements network AIO, which is _COMPLETELY_
 +impossible and broken in _ANY_ micro-thread design. For details
 +and test consider following link:
 +http://tservice.net.ru/~s0mbre/blog/2007/02/10#2007_02_10
 +
 +Designing AIO without network in mind can only be result of heavy hang-over.
 +
 +Kevent AIO is implemented as state machine.
 +There is a patch which implements async open/send_header/sendfile/close.

 -[take35 0/10] kevent: Generic event handling mechanism.
 +[take36 0/10] kevent: Generic event handling mechanism [new description text for generic AIO].

 -Generic event handling mechanism.
 +Generic event handling mechanism [new description text for generic AIO].
 +
 + [ Consider reading at least introduction texts for patches ]

  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
 +
 + It can serve as a storage for different AIO models as well - in case
 + syscall or other request is ready immediately kevent returns that event
 + in submission point.

 + Number of comments dropped to zero several releases ago -
 + it is a sign that API, design and implementation are perfect.
 +
 Consider for inclusion.
