Subject: issues with Kernel#select

Waking up a thread that is waiting in Kernel#select does not appear to work in ruby 1.9  Can someone please confirm that this is the case. Is this the intended behavior, or is this a bug?


> cat a.rb
require 'socket'

pair = Socket.pair(Socket::AF_UNIX, Socket::SOCK_STREAM, 0)
t = Thread.new {
  Kernel.select pair, nil, nil, nil
  puts "Thread is about to exit ..."
}
t.wakeup
t.join

> ruby a.rb
Thread is about to exit ...

ruby 1.9.1p243 (2009-07-16 revision 24175) [i386-darwin10]

> ruby1.9 a.rb   #=> hangs forever!!!!



Any thoughts out there ???

Blessings,
