I had the same thought at first, but I want to ensure that the path
length does not cause trouble anymore.

That's my MacBook Pro with macOS 10.14.5 (Mojave). AFAIK, older versions
can have longer names. Also, I am concerned with accumulating clutter.

The /tmp directory will, with default settings, be cleaned periodically
by the OS, while $TMPDIR (which is user-specific) will not.
