Of course I didn't mean to remove support for TMPDIR completely. You can
have one variable as long as you don't define program-specific variables.

That's correct. I couldn't find any function to unlink a file given its
open descriptor.

I'll probably disable support for NULL as the first argument - its not
used now and I cannot see how it can be used in MC.

Good hit! I was under wrong impression that MC is using g_free()
consistently. I should have learned that consistency and MC don't come
together :-)

I'll fix it shortly.

Again, I agree! This would save us several calls to g_free().
