Yup. Don't do it. Allow instead the creation of files with no
path, which disappear when closed -- hey, better yet, use free memory,
and back them by swap. Hmmm -- sounds suspiciously like unto
mmap(...,open("/dev/null",...),...).
I think the rub is expunging the use of /tmp from all the
applications. (Many of these uses are in the form of mktemp(3)
calls, and several others are fifos.) Once in, it is hard
to expunge such a pervasive kludge...
