-----------------------------------
Integrated in Cassandra #443 (See
[http://hudson.zones.apache.org/hudson/job/Cassandra/443/])
start script causes flapping when used with runit
When started in the foreground, invoke Cassandra using exec so that it
replaces the current shell instead of running it from a sub-shell.

> Starting cassandra in the foreground is the preferred way of running it under
> something like runit or daemontools. Currently, the start script will
> execute java in a subprocess when starting in the foreground. This is a
> problem for runit and daemontools since they both register the pid of start
> script. Occasionally the start script process will fail, leaving the java
> process running. The runit supervisor will then start flapping since it
> thinks cassandra is down even though there is a java process running.
> The attached patch will run cassandra in the same process as the start script
> when run in the foreground. This will cause runit and daemontools to have
> the correct behavior.
