>Description:
Running /usr/tests/usr.sbin/tcpdump/t_tcpdump leaves a temporary directory in /tmp/check.XXXXXX, where XXXXXX is randomly generated each time, having two regular files called `stderr' and `stdout'.

This is probably because the test starts an atf-check(1) process running tcpdump in the background, and then kills that process.  I have no idea what this is supposed to achieve (surely if you kill the atf-check(1) process, it doesn't actually check anything?), but I suspect that killing the atf-check(1) process makes it skip the tempfile cleanup.
>How-To-Repeat:
cd /usr/tests/usr.sbin/tcpdump && atf-run t_tcpdump | atf-report
>Fix:
Yes, please!

Maybe just skip the intermediate atf-check and run tcpdump directly?
