I haven't noticed any slowdown yet. It seems to be an improvement. If
you're good with the patch and could provide me with some text to
write in the commit message (I roughly understand what it does, but I
don't know anything about the other ramifications) I can send another
patch. Otherwise, please feel free to use the patch and commit w/ your
own message/name.

Thanks.
