> Right now, most connectors are firing off the changes to the Observer before the resources acquired by the connector are released, meaning that the Observer cannot use the source within the same thread.  This prevents writing Observers that operate fully before the 'execute(...)' method returns, and requires that any Observer that might need access to the source needs to do its work asynchronously.
> By notifying the Observer _after_ the resources are released but before 'execute(...)' returns, Observers could call back to the source (really through a different connection or at least through a different 'execute(...)' call) to access content.  This means that Observers could be written to work synchronously while still access the (committed) content.
