The relevent code would be using "Synchronized" and
stuff out of JavaX.SwingUtilities especially the
invokeLater() method.  The latter causes the
invokation of the passed method to first clear the
Event Thread.  Ideally, the Event thread should be the
only thread to actually interact with the GUI/swing
objects.  I recently added a bug report about a thread
race condition in the main thread. (I think the Main
thread should first spawn a helper/server thread to do
all it's non-startup work and exit. but that's another story.)
