That you can run both the Python regression tests, and the Stackless
unit tests without any side effects is good enough for me. If this is
the case commit it, but add a comment about the problem and how you
are not sure exactly which registers did the trick.
If you can merge it around to the other branches that are affected by
this problem, that would be good.
