Subject: [PATCH] Kevent, network AIO system calls implementation.

Hello developers.

I'm pleased to announce combined patch of kevent and network AIO
subsytems,
which are implemented using three system calls:
* kevent_ctl(), which fully controls kevent subsystem.
It allows to add/modify/remove kevents and waiting for either given
number or at least one kevent is ready.
* aio_send().
This system call allows to asynchronously transfer userspace buffer
to the remote host using zero-copy mechanism.
* aio_recv().
Asynchronous receiving support.

Next step is to implement aio_sendfile() support.

I hope .. WISH now ACE will support AIO with linux as strong as ms
WIN

Hi Anand,

Thanks for the info. I'm sure that as soon as this stuff is
integrated into the mainline Linux releases the ACE Proactor should
work a lot better!!

Thanks,

Doug

Gentlemen,

This is still work in progress and it will take a while.
aio_suspend () seems to be the key to the issue

Use Reactor in meanwhile. Sometimes
Signal-based Proactor  passes tests, but burns CPU.

Take care.
