"Pull" Functionality
  The Jini(TM) Event Mailbox Service Specification was augmented with additional classes and interfaces that provide synchronous access to events (see sections EM.5-EM.7). Mercury was also updated to implement this new functionality.
  The following work still needs to be done:
  - Implement the timeout functionality for `RemoteEventIterator.next`
  - Make the batching implementation configurable. For example, configuring the number of events that get returned to the event mailbox client in a single call. Currently all the available events are sent.
