Overflow(?) Thread Hang Issue

[Nornec]

Consider the following script, adapted from the main example in the doc:

require "midi-eye"
#puts UniMIDI::Input.gets
@input = UniMIDI::Input.use(2)
midi_listener = MIDIEye::Listener.new(@input)
midi_listener.listen_for(:class => [MIDIMessage::NoteOn, MIDIMessage::NoteOff]) {|event| puts event[:message]}
midi_listener.run

When playing a midi controller very quickly (arguably unnecessarily so), the interpreter hangs without failure or exception, requiring a cmd interrupt. This may just be a limitation of Ruby threads, but I'm positing the potential issue nevertheless.
