Oh, hell... I really wish I'd seen your mail back then ;-/
Would've avoided a lot of headache now (and essentially
duplicating your analysis + patch when a later report
got noticed - right before the -final, Murphy Law being what
it is).

Unfortunately, that approach (and I'd ended up with pretty
much the same patch) doesn't solve all problems in the
area; I think I have a sane fix, will post tomorrow morning...

Again, my apologies. I probably need to do what Linus had
done years ago and unsubscribe from l-k - the traffic is
too high and stuff gets lost in the noise ;-/
