Please commit this to 4.2 as well (assuming SLEEP is also present 
there).  I'm trying to keep the documentation synchronized between the 
two as much as possible, since it needs so much work and the 4.2 release 
is upcoming shortly.

(If you don't have a 4.2 tree handy, let me know and I'll commit it.)
