There seems to be only a documentation bug for this in libc.  mkstemp()
honours the umask, but the man page doesn't mention this.  glibc-2.0.5c's
mkstemp() is similar except it opens the file with mode 0666 instead of
mode 0600.

BTW, I've also seen the tmp file left undeleted in normal operation, and
lots of tmp files left undeleted by (mostly remote?) cvs.

Oops.  The README says 1.71.
