/**

A single instance of this class is owned by the sendas server and is used to

observe background sendas operations, e.g. background sends and launched editors. 

Once an ownership of an operation has been moved to this class, the requesting

subsession may be closed.

When all outstanding tasks are completed, the container notifies the server,

which can then shut down if it also has no open sessions.
