543 * do_specials() is a collection of functions to call from time to time.
544 * Modified 2000-1-14 MSW to use the global pticks count to determine how
545 * often to do things. This will allow us to spred them out more often.
546 * I use prime numbers for the factor count - in that way, it is less likely
547 * these actions will fall on the same tick (compared to say using 500/2500/15000
548 * which would mean on that 15,000 tick count a whole bunch of stuff gets
549 * done). Of course, there can still be times where multiple specials are
550 * done on the same tick, but that will happen very infrequently
551 *
552 * I also think this code makes it easier to see how often we really are
553 * doing the various things.
