Note that 'context_lock_struct' (assuming that's the new name) can be
used to just forward declare structs, too, so 'define' in the name is
probably incorrect. And to avoid more levels of indirection I'd just
stick with one name; if 'context_lock_struct' isn't too offensive to
anyone, that'd be the name for the next version.
