Hmm, I'm not quite sure how this works. :) You appear to be referring to
two different updaters (updater and this.updater), but they actually refer
to the same object because the function is unbound, and updater is a global.
And sadly, I was wrong the whole time, PeriodicalUpdater doesn't use a
setInterval(), but a delayed function call. You can change the frequency
value at any time by calling updater.frequency = newValue.
Sorry for the wild goose chase, but you learned something right? ;-) (Like,
don't trust people who post to mailing lists?)
