	What I don't understand about all this (and I won't, unless I
look at the code) is why they are setting the file descriptor to -1
anyhow. That seems kind of dubious to me.

	stdio is well behaved and works portably unless you start to
grub around in its private data. fclose() is a better way of disabling
a FILE * than setting its file descriptor to -1, and fdopen() is a better
way of wrapping a FILE * around an existing file descriptor.
