36   rules for mk[s]temp (i.e. end in "XXXXXX", possibly with a suffix).

38   gen_tempname.  TMPL is overwritten with the result.

42                        at the time of the call.
43   GT_FILE:             create a large file using open(O_CREAT|O_EXCL)
44                        and return a read-write fd.  The file is mode 0600.
45   GT_DIR:              create a directory, which will be mode 0700.
