git-p4: add trap to kill p4d on test exit

larsxschneider · peff · commit dfe90e8b528b · 2015-11-20T08:02:06.000-05:00
Sometimes the "prove" test runner hangs on test exit because p4d is
still running. Add a trap to always kill "p4d" on test exit.

You can reproduce the problem by commenting "P4D_TIMEOUT" in
"lib-git-p4.sh" and running "prove ./t9800-git-p4-basic.sh".
