This, acquire/release are RCpc, while (with the exception of Power)
LOCK/UNLOCK are RCsc.

( Or did we settle on RCtso for our release/acquire order? I have vague
memories of a long-ish thread, but seem to have forgotten the outcome,
if any. )

Lots of subtlety and head-aches right about there. Anyway, it would be
awesome if we can get Power into the RCsc locking camp :-)
