Works for me as long as all clients check the optional and use it correctly. It
allows for multi-thread safety so that is good. Not sure if std::optional is
actually threadsafe though, but the timing required to make this fail would be
pretty low percentage. If it were me I would make it bullet proof as just leak
the map as when we tear down the process, any allocated memory will just go
poof anyway and it will actually speed up the process teardown process as no
work will need to be done to clear this map, though it should really be empty
anyway.
