Yecchhhh...  Applied, but it's very ugly.  Oh, well - regression is
regression, and I don't see a cleaner fix at the moment.  If I don't
manage to come up with anything prettier, to Linus it goes in tonight
pull request ;-/

Please don't. That thing is too ugly to exist. It also looks
completely and utterly buggy. There's no way I'm taking it. If
switch-names is suddenly conditional, what the f*ck happens to the
name hash which is unconditionally done with a swap() right
afterwards.

The sucker's unhashed after that...  And yes, I agree that it's fucking
ugly.  Still looking for saner ways to do that...
