That is why I would appreciate some extra pairs of eyes on this :) I
tried to be as careful as possible when refactoring this, but since it
is quite convoluted something might have slipped through. The testsuite
does not show anything, but there might be corner cases that are not
tested I guess.
Will hopefully have time to look into the comments to the main patch of
this series tomorrow. Did not get around to properly do that yet.
