Element in the CommSpace for communication. This is what gets written to the CommSpace

XXX does this need to exist or can I just stick Objects in the CommSpace?

XXX because the val field is final, its impossible to re-use a CommSpaceElement (i.e., for a different object...) Could work around this by making the val field read-only while the object was lodged in the CommSpace...

XXX these are shared between processes.... i.e., they leak (~2 words).
