An obvious idea that comes to mind is to advise the
`self-insert-command' function. Can functions written in C be
advised? (I don't know, I never actually *used* advice.)
If this is not possible, one could remap all self-inserting commands
to e.g. `self-insert-if-not-repeated-too-many-times', which could be
trivially defined to Do The Right Thing™ (possibly using something
like (looking-back "\\(.\\)\\1")).
Note: do you mean "when the user types 3 or more of the same character
in a row", or rather "when a user types a character such that two
characters before point are this very character, too?" My suggestion
deals with the latter variant, of course, which encompasses more cases
than the former, but seems reasonable to me.
