@RogerRiggs , as Aleksey pointed out `ProcessHandle::toString` isn't specified
to return the string which contains only
`pid` (in fact it's not specified at all), so I don't think we should rely on
the current implementation.
although it doesn't matter much, I've removed explicit conversion here and
replaced `String::valueOf` with
`Long::toString` in other places.
