[PATCH] Service status self-description
I am adding code to all my application-specific Turbine services to give them
the ability to describe their current status. For instance, I have a service
which performs a complex action on demand; it keeps track of the number of
successes and failures, and the average time the action takes to execute. I'm
going to make this information accessible to an admin of my app, and similar
information for my other application-specific Turbine services.
The following is a patch which adds a new method (public String getStatus()) to
the Service interface, so that it's easy to add this sort of capability to your
Turbine services. Simple implementations are provided for BaseService and
BaseUnicastRemoteObject; they display whether or not the service has
been initialized.
Let me know whether you think this feature would be generally useful in Turbine.

This is great! I really like the move towards enabling services to
describe themselves in a human-readable fashion. +1
