 * 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.
