// * Tests the following sequence of events:
// * 1) Lock is acquired in UI thread
// * 2) Modal context thread is started using IThreadListener
// * 3) Lock is transferred to modal context thread
// * 4) Modal context thread performs an asyncExec
// * 5) The asyncExec tries to acquire the same lock held by the modal context
// * 6) The modal context thread exits, thus transferring the rule back to the UI thread
// * <p>
// * Now the rule has been transferred back to the UI thread, but the UI thread
// * is in a wait loop waiting to obtain the rule. The UI thread should realize that
// * it now owns the lock it is waiting for, and continue with its execution.
// * <p>
// * See bug 98621 for more details.
