[java-gnome-hackers] threads

Hi,
  I think you've already found that gtk, like swing, requires that
almost all graphics operations must be performed in a single thread. 

Your timer looks interesting, but I think this would only be useful for
a limited number of cases. Perhaps it would be more useful to create
methods similar to SwingUtilities.invokeAndWait(Runnable) and
SwingUtilities.invokeLater(Runnable), which execute the run method of
the given class in the graphics thread. These methods are used for
everything which updates the display from additional threads. 

I was going to suggest at this point that Timer could be based on those,
but now realise that it would probably have severe performance issues.
So it's probably best if we have both a timer and invokeLater (or
similar) methods.

For your API Proposal, I would suggest that you make it more like the
Thread class, in that the user can either override it (e.g. if they want
to change it's functionality), or they can supply a Runnable object to
its constructor (when they want to use the default behaviour).
