I'd prefer to bind it to "~" to make sure it's writable too (just in
case).  Also, emacs run as root doesn't risk polluting "/" with
spurious temporary files if there is some writing going on when there
shouldn't be.  Or we could use the same value as
url-temporary-directory: (or (getenv "TMPDIR") "/tmp")

Not sure if we want a general facility here, but I guess that depends
on how common these kinds of issues are.
