Prototype doesn't do anything to remove the handlers on `remove`,
they'll stay in memory.
If you know you've only set handlers on that element and none of its
children, yes, use `stopObserving`:
$("theElement").stopObserving().remove();
If there may be handlers on the element's children as well, use
`purge`[1]:
$("theElement").purge().remove();
It's not clear from the documentation, but `purge` does remove
handlers from the element's descendants.

And of course, in quite a few cases event delegation might be a better
solution to start off with, either on the parent element or the window
object itself.
