/*
 * Always detach the main thread so that it appears to have ended when
 * the application's main method exits.  This will invoke the
 * uncaught exception handler machinery if main threw an
 * exception.  An uncaught exception handler cannot change the
 * launcher's return code except by calling System.exit.
 *
 * Wait for all non-daemon threads to end, then destroy the VM.
 * This will actually create a trivial new Java waiter thread
 * named "DestroyJavaVM", but this will be seen as a different
 * thread from the one that executed main, even though they are
 * the same C thread.  This allows mainThread.join() and
 * mainThread.isAlive() to work as expected.
