Comment (by vbraun):
I ran `strace -ff -o /tmp/log/trace -s 128 sage -tp
doc/en/constructions/linear_algebra.rst` on my desktop and there isn't
much going on in the file system:
{{{
$ grep ^unlink *

}}}
The only obvious race is #13826, though I don't think that could cause the
lisp failure. All communication with Maxima goes through a pty.
