Subject: Block method to yield stdout?

All, I've written a distribution service that spawns processes using  
IO.popen in a seperate thread for each job.

In my Task class, I would like to create a block method such as  
'Task.monitor(mode="stdout")', which would yield the stdout for that  
task from that point forward. -- similar to tail -f, but for a  
multithreaded environment.

The result would in essence be called like:

task = Task.new(:cmd => "tail -f /some/log")
sleep 10
task.monitor
# fresh content from some/log will be yielded


Since $stdout is global, what would be the beat way tackle this?
