Not getting snotty with you Andrey but the program that I wrote, and
which I'm currently tweaking, is currently being used by a dozen of my
colleagues in five countries that I know of.

Occasionally a thread freezes up . . . . and rather than have the
frustration of having to close and re-open the program, I just abandon
the thread. Obviously this would get hairy if a thread froze up every
20 seconds, but it rarely happens -- more like once or twice a day.

But this isn't about the one program that I wrote. I think in general
an 'std::optional' should be able to abandon its object.
