Hi Maxim,

While we are coming from different sides on this, I do want to thank
you for your input on libevent and epoll. It is a positive
contribution to the discussion. Please see below for my replies.

I believe that an epoll-based implementation (not an exposed
interface) would be one of the most likely. I'm really not dis'ing
epoll's use, just where it is used.

That is good news for the Linux platform, but it doesn't change
things in the general case.

I agree with the progression of better-ness all the way to "as simple
as one can get". I think it can be much simpler.

I guess a "perfect corner of the world" would be more accurate :).
libevent is GPL, which for me is a full stop on its use and I cannot
(politely<g>) say just how much I dislike C driving my C++
programming. While I came from a C background, I want to see pure C++
solutions for my problems. They are safer, easier to understand, use
and maintain, but let's not get into a debate on such ethereal issues
in this space. I think most folks using boost would agree: GPL evil,
C bad, C++ good. ;)

Best,
Don
