title: Stop Grails from opening a connection to the database in a Controller method
body: <p>I have a service that is communicating to another machine.  Since it's a simple Controller method Grails automatically grabs a DB connection from the pool while my controller is communicating with the other server.  I'd like to prevent it from doing that, and manually open up the database connection when I'm ready so that it doesn't suck up a connection during a long period like doing network calls.  How do I prevent Grails from automatically grabbing a connection from the pool in a controller method?</p>
