If you need to lock, then your method is not const. Conversely, if the object
is guaranteed to be identical before and after the method call, then the
methiod does not need to lock any mutex.
I don't agree with your line of reasoning, and it seems that the C, POSIX and
C++ don't either - otherwise they'd have lock and unlock as immutable methods
