"glocal_string" is really "glocal_free", or at least that's what
I called it in my version, because you can use it on anything
that you know can be freed with g_free(), which isn't just
strings.  For example, private structures.

Ah, of course. Makes a lot more sense.

Hmm.  What's the use case for this one?

I use it for the automatic unlocking macros for example. Or to close a stream/fd, or to do manual profiling of hot spots - you just have one ifdef block at the top, and not littered all over the function at all return points, or if you're building some kind of message that you must always write() to a pipe before returning, etc.
