Hi metze,

There is already logic in ctdb to clean up child processes if the main
daemon goes away.  The problem here is of shutting down the local ctdb
daemons when autobuild.py terminates abnormally.

Here's a patch that shuts down the local daemons started for test if the
run_tests.sh script is sent SIGINT or SIGTERM.  I have tested it by running
autobuild.py and then pressing Ctrl-C. This sends SIGTERM to run_tests.sh
and shuts down the local daemons.  So as long as autobuild.py terminates
the child processes, this would work.
