Is this a bug in Ruby or my brain? :-)

$ sizedqueue.rb=20
quire 'thread.rb'
q =3D SizedQueue.new(0)
Thread.start { q.pop }
q.push 1=20

$ ruby sizedqueue.rb=20
deadlock 0x80fb99c: 2:0  - /pack/ruby-1.6.7/lib/ruby/1.6/thread.rb:184
deadlock 0x8105d98: 2:0 (main) - /pack/ruby-1.6.7/lib/ruby/1.6/thread.rb:253
/pack/ruby-1.6.7/lib/ruby/1.6/thread.rb:253:in `stop': Thread: deadlock (fa=
tal)
        from /pack/ruby-1.6.7/lib/ruby/1.6/thread.rb:253:in `push'
        from sizedqueue.rb:4

Or is there an easier way to do job/thread multiplexing without a queue? I.=
e.
to have all pushers block until someone pops.
