Oh.

It's such a game: twice a year someone sends this patch to mail list.

I have another one for you:
* Find all the patches equal to this one in archives.
* Read all the discussions.
* Come back if you have some new ideas, not already discussed many times here.

Sorry for my sarcasm.
NACK for this, as usual.

Best regards, Ilya Maximets.
