-/**
- * This component manages a {@link MailboxClient} for each mailbox we know
- * about and are able to use (our own mailbox and/or contacts' mailboxes).
- * The clients are created when we come online (i.e. when the Tor plugin
- * becomes {@link Plugin.State#ACTIVE active}) and destroyed when we go
- * offline.
- * <p/>
- * The manager keeps track of the latest {@link MailboxUpdate} sent to and
- * received from each contact. These updates are used to decide which
- * mailboxes the manager needs clients for, and which mailbox (if any) should
- * be used for uploading data to and/or downloading data from each contact.
- * <p/>
- * The assignments of contacts to mailboxes for upload and/or download may
- * change when the following events happen:
- * <ul>
- *     <li> A mailbox is paired or unpaired </li>
- *     <li> A contact is added or removed </li>
- *     <li> A {@link MailboxUpdate} is received from a contact </li>
- *     <li> We discover that our own mailbox's supported API versions have
- *     changed </li>
- * </ul>
- * <p/>
- * The manager keeps its mutable state consistent with the state in the DB by
- * using commit actions and events to update the manager's state on the event
- * thread.
