Trying to get away with something.

Not the same situation, violation rather than a foul, but I believe that this caseplay shows the purpose and intent that the NFHS wants us to use in such situations:

Keep in mind that the NFHS doesn't have "clear path fouls" so we often have to improvise.

NFHS 9.3.3 SITUATION D: The score is tied 60-60 with four seconds remaining in the game. A1 has a fast break and is near the free-throw line on his/her way to an uncontested lay-up. B5 running down the court near the sideline, runs out of bounds in the hopes of getting a leaving-the-floor violation called. RULING: B5's intentional violation should be ignored and A1's activity should continue without interruption. COMMENT: Non-contact, away from the ball, illegal defensive violations (i.e. excessively swinging the elbows, leaving the floor for an unauthorized reason) specifically designed to stop the clock near the end of a period or take away a clear advantageous position by the offense should be temporarily ignored. The defensive team should not benefit from the tactic. If time is not a factor, the defense should be penalized with the violation or a technical foul for unsporting behavior. (10-1-8)

That's what I would do under NFHS rules, "wait and whack".

What does one do under other rule sets?

I honestly and literally don't have a clue.
