Bug #2469: Difference behavior of IO#read_nonblock and #read between 1.8 and 1.9
http://redmine.ruby-lang.org/issues/show/2469

Author: ujihisa .
Status: Assigned, Priority: Normal
Assigned to: Koichi Sasada, Category: core, Target version: 1.9.x
ruby -v: ruby 1.9.2dev (2009-12-10 trunk 26055) [i386-darwin9.8.0]

The following code doesn't finish on ruby 1.9 (both 1.9.1 and 1.9.2dev), while finishes with Errno::EAGAIN on ruby 1.8.7.

read, write = IO.pipe
write << 'hello'
read.read_nonblock(5)
read.read(5)

I checked it on i386-darwin9.8.0 and i686-linux.
(This code is extracted from spec/rubyspec/core/io/read_nonblock_spec.rb)
