Well, (1) finding a place to put the temp file, ie a writable directory;
(2) ensuring the file is removed afterwards; (3) not exposing the user
to security hazards due to unsafe use of a temp file (ye olde
overwrite-a-symlink risk). Perhaps a few more I didn't think of.
It's not a trivial change, and the evidence presented so far hasn't
convinced me that we need to put in the effort.
