GObjects can now register a timer with the GEventLoop. This will eventually cause GTimerEvents to be dispatched to the GObject. This needed a few supporting changes in the kernel: - The PIT now ticks 1000 times/sec. - select() now supports an arbitrary timeout. - gettimeofday() now returns something in the tv_usec field. With these changes, the clock window in guitest2 finally ticks on its own.
