[issue14502] Document better what happens on releasing an unacquired lock

[Jim Jewett]

Vinay,

The current question is what contract locks should follow, and whether
all locks should follow it.  Would it be acceptable for
logging._releaseLock to raise a RuntimeError if the lock hadn't
previously been acquired?  In other words, would it be acceptable to
replace the current None with a counter (and to note in comments that
it should be safe from race conditions because it is only used when
threading isn't available).
