 * This is completely separate from the above, and is the
60
 * "new and improved" way of handling timers more dynamically.
61
 * Hopefully efficient and general enough for most things.
62
 *
63
 * The "hardcoded" timers above are still useful for well-
64
 * defined problems, but the timer-list is probably better
65
 * when you need multiple outstanding timers or similar.
66
 *
67
 * The "data" field is in case you want to use the same
68
 * timeout function for several timeouts. You can use this
69
 * to distinguish between the different invocations.
