Subject: errors with monitor

getting this error in a synchronize call:

/usr/lib/ruby/1.8/monitor.rb:212:in `mon_enter': undefined method `+'
for nil:NilClass (NoMethodError)
  from /usr/lib/ruby/1.8/monitor.rb:236:in `synchronize'


class definition is here:

class SyncPipe < IO
  include MonitorMixin

  def initialize( p )
    @file = IO.popen( p )
  end

  def puts( output)
    synchronize do
      @file.puts(output)
    end
  end

  def close
    @file.close
  end
end

The idea is to have a pipe that threads can write their output too
without interfering with each other....

Any idea what is going wrong. I had this working at one stage, sigh...
