Ooh, that's so hard.  std::unique_lock supplies unlock() and lock()
primitives, but it provides the very convenient guarantee that any lock
will be released when it goes out of scope.

Honestly, I don't know why you feel empowered to criticize tools you
don't use and don't understand.  You are certainly not required to use
C++ in your drivers, but you are entirely out of line to argue that C++
is inherently inferior.  It is provably not so.
