I got really into playing pinball a few years ago, and I got into the habit of turning of a pinball machine whenever it wasn't working correctly (mis-aligned flippers, whatever) so that other people didn't waste their quarters. Yes, it was kind of obnoxious. Sorry.

Anyway, a similar mechanism to say "hey, this voting machine might be screwed up, somebody check it out ASAP!" would make a lot of sense.
