I could see including both clobbering and non-clobbering flavors of

We already get clobbering versions of sei()/cli() locks
inside ATOMIC_BLOCK() and friends.  Won't that do it instead
of new versions of sei()/cli() (or whatever name)?

Yes, that makes perfect sense. Maybe we should capture the essence of this e-mail thread and include it in the avr-libc documentation so that the difference between the two is clear. After all, every once in a while somebody *does* read the documentation :)
