/*
* This is completely separate from the above, and is the
* "new and improved" way of handling timers more dynamically.
* Hopefully efficient and general enough for most things.
*
* The "hardcoded" timers above are still useful for well-
* defined problems, but the timer-list is probably better
* when you need multiple outstanding timers or similar.
*
* The "data" field is in case you want to use the same
* timeout function for several timeouts. You can use this
* to distinguish between the different invocations.
