I like it, but I'd put lock_sleep in kern_lock.c and wouldn't make 
lockstatus_owned public.
I like it too. Having the lock as the first or last arg makes much more 
sense than having it in the middle.  It won't be confusing, especially 
when we document it in a manual page and in porting_drivers.txt.

+10, should go in now.  However then we'd ship a release with a lot of 
deprecation warnings.  Maybe we should follow up with a 
msleep->spin_sleep commit.
