This component still needs to have better comments on the synchronous/
asynchronous model.  As far as the calls needed for the gui, all the
basic button functions for threads, i.e. continue, step, breakAll,
setBreakpoint, they are all covered.  We also have a way of notifying
various other GUI components when a breakpoint is set.  This part is
still a bit dubious, I'm not sure how the GUI is going to handle getting
callbacks into itself.  However, based on our GUI design, I think that
it is better to not have GUI components depend on each other.

I am unclear about the importance of monitorGlobalValue, as we don't
have a way to detect global values at the moment.  (I think
monitorThreadValue will suffice for this task.)
