# Test `zenity --list` with named pipes.
#
# Based on a script written by Falan Orbiplanax, reported in Zenity issue #71
# on GitLab. I gave up on getting the script to run correctly from the Zenity
# test-suite, because no matter what I tried to modify it, it would almost
# always result in a stale process that would not die. At this time, it should
# be run manually. The test is considered successful if the program runs to
# termination without a segfault.

# Pesky script won't DIE!! This is what finally gets it to do so. Since SIGTERM
# exit status is 143 typically, we'll test for that exit status to see if the
# test "passed". Grrr....
