Subject: signaling another thread



what is is the prefered method in which one thread can 'signal' another thread
on some condition?  Observable?  other?

eg.

  other = Thread.new {
    do_important_work
  }

  watch = Thread.new {
    loop {
      notify(other) if some_test_that_should_interupt_important_work
    }
  }


one thing i've considered doing is something like

  worker = Thread.new{stop; do_work}
  watcher = Thread.new{stop; loop{check or worker.stop}}

  watcher.start
  worker.start

perhaps this model would be best done using another process and signals since
the potential for the watcher to be put to sleep at a critical time is larger
with threads...

thoughts?
