Subject: Re: Monitor Error when Joining Threads

All,

So this doesn't have anything to do with Thread.join and such... it 
instead has to do with some synchronization I'm doing in another class. 
Here's what it looks like:

class StatsTracker < Monitor
  include Singleton
  ...
  def foo
    synchronize do
      # do something
    end
  end
  ...
end

I get an error at the 'synchronize do' line similar to what I describe 
in my first post, essentially saying @mon_count is nil.  I tried 
including MonitorMixin vs extending Monitor, but that didn't fix the 
problem.  I then tried doing the following and it worked:

class StatsTracker
  include Singleton
  def initialize
    @semaphore = Mutex.new
  end
  ...
  def foo
    @semaphore.synchronize do
      # do something
    end
  end
  ...
end

Does anyone know what I'm doing wrong to make the Monitor approach not 
work?
