The standard requires overloads of std::to_chars for char and (un)signed
integer types. This means that our constrained function template is
non-conforming, because the difference is observable when using types
that convert to an integer (e.g. wchar_t, which promotes).

There was a race condition if the loads occurred in parallel, but
basically the first device would get loaded correctly, and the second
