"Complex is better than complicated... Special cases aren't special enough to break the rules."

The module "regrtest" is complex enough. We don't need to keep useless hacks inside.
It would be more interesting to replace the hack with some words, or an assertion, and understand the real (or hypothetic) issue behind this hack.

Eventually, if we keep these hacks around, it may hide real bugs.
