  No amount of unit tests can catch all possible bugs. You may have a
thousand unit tests for a small module, yet there may still be bugs there.

  In some cases these bugs *might* be triggered by seemingly unrelated
changes somewhere else in the program, even if there is no connection
between the two modules (might be less likely in "safe" languages, but
probably not impossible).

  Unless running the unit tests takes hours, does it hurt to run them?
