Err, okay. I did use the word "stable" with tests rather than "correct", and I implied upthread that I did not check the correctness nor the internals of the patch. If my words held the meaning you are implying, well, my apologies for the confusion, I guess. I only tested the patch and it was stable while I've noticed a few diffs with the previous version, but I did *not* check its internals at all, nor do I mean that I endorse its logic. I hope that's clear now. -- Michael
