/**
* Starts a long running (application) Thread that will run through commands
* that require remote mailbox access. This class is used to serialize and
* prioritize these commands. Each method that will submit a command requires a
* MessagingListener instance to be provided. It is expected that that listener
* has also been added as a registered listener using addListener(). When a
* command is to be executed, if the listener that was provided with the command
* is no longer registered the command is skipped. The design idea for the above
* is that when an Activity starts it registers as a listener. When it is paused
* it removes itself. Thus, any commands that that activity submitted are
* removed from the queue once the activity is no longer active.

* 25k for a "small" message was picked by educated trial and error.
* http://answers.google.com/answers/threadview?id=312463 claims that the
* average size of an email is 59k, which I feel is too large for our

* 25 random messages.
* <pre>
* 5k - 61 seconds,
* 25k - 51 seconds,
* 55k - 53 seconds,
* </pre>
* So 25k gives good performance and a reasonable data footprint. Sounds good to me.
