Whatever, your patch is more buggy that the code that previously exists
then it will be reverted. The real issues will be addressed, in a
cleaver way (I hope) by someone who really understands what the code is
supposed to do.
But the more important issue is: DO NOT COMMIT IN THE CODE YOU'RE NOT
SUPPOSED TO CHANGE WITHOUT REQUESTING AN AGREEMENT. This is not
negociable AT ALL.
