Hi
I have some problems with RunnableQueue.
I've read that UpdateTracker is _not_ intended to be
thread safe, but UpdateTracker.changeStarted() is
called outside the UpdateManager thread when resizing
the SVGCanvas. sometimes this could finnish with a
ConcurrentModificationException in UpdateManager.
Here are stack traces for AWTEventDispatchThread and
the ConcurrentModificationException in UpdateManager
