We need to be able to access the SafeRunnable in JFace in order that some error protection can be added to preferences and properties dialogs.

/**
 * Runs the given <code>IRunnableWithProgress</code> in this context.
 * For example, if this is a <code>ProgressMonitorDialog</code> then the runnable
 * is run using this dialog's progress monitor.
 *
 * @param fork <code>true</code> if the runnable should be run in a separate thread,
 *  and <code>false</code> to run in the same thread
 * @param cancelable <code>true</code> to enable the cancelation, and
 *  <code>false</code> to make the operation uncancellable
 * @param runnable the runnable to run
 *
 * @exception InvocationTargetException wraps any exception or error which occurs 
 *  while running the runnable
 * @exception InterruptedException propagated by the context if the runnable 
 *  acknowledges cancelation by throwing this exception.  This should not be thrown
 *  if cancelable is <code>false</code>.
