Well, for some strange reason I didn't observe the problem on a couple
of old macs here, might have got lucky or something (could depend on
whether might_sleep() is compiled to do something or not... depends
on .config debug options).

Anyways, I'll send that fix to Linus asap. Thanks for reporting !

Cheers,
Ben.
