Wouldn't the second approach still have the same drawback as the first
in regards to Ant tasks? At least if you wanted to shut down
gracefully and cleanup after the shutdown (closing connections,
streams, etc).
I do like the idea of issuing a stop command to an already running
build, like sending the stop command to tomcat. That would give a
more graceful exit and means of stopping a build that gets out of
control than using ^C.
