kgio provides non-blocking I/O methods for Ruby without raising  
exceptions on EAGAIN and EINPROGRESS. It is intended for use with the  
unicorn Rack server, but may be used by other applications (that run on  
Unix-like platforms).

Note: I do not recommend using kgio for future applications, Ruby 2.x  
has a lot of the functionality of kgio and Ruby 2.3.0 (due in December)  
will have even more (with more improvements planned).  
Keep an eye on the NEWS file for Ruby 2.3+ releases.  
However, I'll continue maintaining kgio for legacy purposes  
indefinitely.

Changes: kgio 2.10.0 - slimming down...

&nbsp;&nbsp;&nbsp;&nbsp;The largely-unused autopush functionality is now a no-op.  
&nbsp;&nbsp;&nbsp;&nbsp;Existing applications will probably not notice, and are  
&nbsp;&nbsp;&nbsp;&nbsp;better off using MSG\_MORE anyways if they're on Linux.

&nbsp;&nbsp;&nbsp;&nbsp;Our poll(2) wrapper now uses rb\_hash\_clear if available,  
&nbsp;&nbsp;&nbsp;&nbsp;reducing global method cache dependence.

&nbsp;&nbsp;&nbsp;&nbsp;shortlog of changes since 2.9.3:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;README: remove reference to Rainbows!  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;writev: update comment on preserving errno  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;poll: avoid rb\_funcall for rb\_hash\_clear  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;minor doc updates  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;remove autopush support and make it a no-op  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;HACKING: update URL for Message-ID lookup
