I think I was wrong in [ruby-talk:40015] -- although, I can't
verify it now.  On Linux, #select returns nil on timeout.
Maybe on Win32 it returns [[], [], []] ... I can't remember.

I just ran Wilkes's test case on Linux, and #select returns
nil even with the Thread.new line not commented out.

I think the problem has to do with threading interfering with
#select on Win32.  [ruby-talk:40221] reminds me of this ...
and the next message [ruby-talk:40279] you post a patch.
