It's not so much a question of changing test results (although
obviously that is a side-effect) as there are GAP packages that change
the behavior of GAP, sometimes in significant ways.  Therefore code
that uses GAP sometimes may need additional logic to account for
differences in results that occur depending on what packages are
loaded.  It's quite frustrating and confusing.
