/*
* An application may require immediate access to JMS. So we need to block here until the service
* has started. How long ActiveMQ requires to actually create a broker is unpredictable.
*
* A broker in OpenEJB is usually a wrapper for an embedded ActiveMQ server service. The broker configuration
* allows the definition of a remote ActiveMQ server, in which case startup is not an issue as the broker is
* basically a client.
*
* If the broker is local and the message store contains millions of messages then the startup time is obviously going to
* be longer as these need to be indexed by ActiveMQ.
*
* A balanced timeout will always be use case dependent.
