No we shouldn't slow them down. I'd be interested to see whether

OTOH, maybe you don't need a new data structure. Maybe you could
use the hash and check that for a match on a private futex before
trying to find a possible shared futex.

Locking I guess becomes no more of a problem than now, and in some
cases maybe much less. So OK, I stand corrected.
