Bug #2637: unable to select for < 0.1s in windows
http://redmine.ruby-lang.org/issues/show/2637

Author: Roger Pack
Status: Open, Priority: Normal
ruby -v: ruby 1.9.2dev (2010-01-24 trunk 26391) [i386-mingw32]

in 1.9:
 >> a = TCPSocket.new 'google.com', 80
 >> Benchmark.realtime { IO.select([a], nil, nil, 0) }
 => 0.109375

in 1.8
>> a = TCPSocket.new 'google.com', 80
>> Benchmark.realtime { IO.select([a], nil, nil, 0) }
=> 0.0

This slow downs drb *a lot*, so is somewhat of a blocker.
Thanks.
