That's a sign that we should, additionally, have
        on_exit 'kill `cat *.pid`'
or similar embedded in the test.  Otherwise if some part of the test
before OVSDB_SERVER_SHUTDOWN fails, nothing will kill the database
server and the test will hang anyway.

(It looks like other tests in ovsdb-idl.at have that problem too.)
