The build infrastructure could explicitly set $TMPDIR (or %TMP% on Windows) to an empty directory and at the end of a successful build check that the directory is still empty. If not, it could fail.

Or we could do it in cmd/dist test, perhaps optionally.

Non Windows users might struggle if they do not know that you cannot delete running executable on Windows, you cannot delete opened file on Windows, you cannot remove directory if it is current directory on Windows and similar.
