I'm planning on queuing this up for 2.6.37.
Honestly, this is mainly just to make a few pynfs tests pass more
reliably, which isn't a good enough reason on its own.
But I also can't see any problem with letting the laundromat thread run
as much as once a second.

nfsd4: expire clients more promptly
Expire clients more promptly, at the expense of possibly running the
laundromat thread more frequently.
Though it's not the default, I'd like it to be feasible to run with a
lease time of just a few seconds, at which point a minimum 10 second
wait between laundromat runs seems a little much.
