Folks,

NIO extensions (first take) are ready for review. Feel free to take a
look and let me know what you think. Feedback, suggestions, critique
will be highly appreciated.

I wrote a short description of the HttpCore NIO API the best way I
could:

http://wiki.apache.org/jakarta-httpclient/HttpCoreNioApi

There are also a couple of samples to show the new API in action.

It is premature to draw any conclusions yet but preliminary test results
show that NIO tends to perform significantly worse under heavy load than
the classic I/O. I'll be doing more tests with various scenarios (small/
large content entities, POST/GET request types, lots of idle connections
and a few ones under heavy load, and so on) to make the picture more
complete.

Oleg
