Can a route shut itself down?

[Adrian Trenaman]

Hi Community,

I'd like to be able for a route to be able to intelligently shut itself 
down: for example, if the route discovers that a DB connection or some 
other back-end service is unavailable, then it should gracefully shut 
itself down and then be restartable through human intervention, for 
example, through JMX.

Thoughts?

Best,
Ade.
