Jay Kreps updated KAFKA-328:
----------------------------
Description:
Background discussion in KAFKA-320
People often try to embed KafkaServer in an application that ends up calling
startup() and shutdown() repeatedly and sometimes in odd ways. To ensure this
works correctly we have to be very careful about cleaning up resources. This is
a good practice for making unit tests reliable anyway.
A good first step would be to add some unit tests on startup and shutdown to
cover various cases:
1. A Kafka server can startup if it is not already starting up, if it is not
currently being shutdown, or if it hasn't been already started
2. A Kafka server can shutdown if it is not already shutting down, if it is not
currently starting up, or if it hasn't been already shutdown.

Background discussion in KAFKA-320
startup and shutdown needs to be fixed to ensure correct behavior on repeated
calls to the API. One of the possible checks would be -
1. A Kafka server can startup if it is not already starting up, if it is not
currently being shutdown, or if it hasn't been already started
2. A Kafka server can shutdown if it is not already shutting down, if it is not
currently starting up, or if it hasn't been already shutdown.
