I suppose one thing that could be done is to set opp->file and opp->file_len
regardless of whether mkstemp() succeeds or not, that is lines 1987:1093 in
unix.c, and then in open.c:new_unit() one can free opp->file after generating a
suitable error message.
Even if the file name is automatically generated, maybe it would be helpful to
provide the user with info exactly what failed, e.g. so that the user knows
what failed was opening a file under /tmp which might otherwise not be obvious
to the user.
