And btw, looking closer, I see that this is a regression in Emacs 28,
which was caused by a change in Gnulib: the versions of tempname.c
that we used up to and including Emacs 27.2 used gettimeofday and the
PID to generate the file name, so it was more random than the code in
current Gnulib, and in particular the sequence of
generate file-name1
delete file-name1
generate file-name2
would produce file-name2 that is different from file-name1. With the
current code in Gnulib, something similar happens only on glibc
systems. So I hope the code in Gnulib's tempname.c will be amended to
call clock_gettime or something similar, so that the names on
non-glibc platforms could also be random. Or, failing that, at least
that gen_tempname in glibc would behave identically to other systems,
i.e. start from a fixed "random" value.
