Well, maybe. Maybe not. I tend to program in C; and as a C programmer I
*don't* want RTLD_GLOBAL --- that just ends up polluting the global namespace
and can cause serious issues if, for example, a plugin provides a symbol
that's also defined in the main program. For me, RTLD_LOCAL is nearly always
the right solution.

Lua is not supposed to be a one-size-fits-all solution. You're *supposed* to
modify it to fit your needs. RTLD_LOCAL is the principle-of-least-surprise
preferred default for C; it prevents plugin Y's behaviour from being changed
depending on whether you load plugin X beforehand. I'd be very wary about
changing this default merely because it suits C++ better.
