I assume this means any call to getsafereadpointer()/getsafewritepointer()
will increment the lock count.  So the UnlockObject() calls will be
mandatory.  Either that, or you'll have an explicit LockObject() call as
well.  What behavior should happen when a resise is attempted while the
lock count is positive?
