But it's actually safe for lots of threads to read the variable
simultaneously. It's just tough to tell whether an access is a read or
update...
You're right, though. More emphasis is necessary, and a more complete

Just out of curiosity, why? I presume it's unlock in addition to locks
getting released when they fall out of scope. I can see the occasional
need, but I don't know that it'd be used enough to justify the extra
hassles involved.
