[DUG]Timers

[Matthew Comb]

Carlos' code looks good and synchronizes the time event with the main thread.

Be aware though that the thread timeout in these components does not take
into account how long it took to execute the event.

In johns case if his code executed took 20 seconds for example, and the
resolution on the timer is 30 seconds, then the combined resolution would
be 50 seconds.

If resolution is really important, you would be better to segment your
timer code in another worker thread.

This doesn't matter much if the event code is negligable.

Matt.
