When we run stress.bat we see that we get a
with each Regedit-iteration.
This was also wrong with r72494, see log72494, but we had no user visible symptom back then.
With r72495 we removed that exception handler and therefore we do not longer hide the underlying issue.
As a result each iteration now gives a crash-box, see log72495
Preferably we should fix the underlying issue asap.
If we can not manage this until 0.4.3 release, we should consider temporarilly reverting r72495 as a release-hack.
I consider this a 0.4.3 blocker.
