Re: Question about context attributes

This is a very good question!

The problem is that context attributes are frequently used as configuration
passed from the environment into the context.  Thus you don't want
to blow away configuration over a stop/start cycle.  So we currently don't
clear the attributes.

But thinking about it - I think we should.   The configuration stuff
will have to be set on every start - and there are plenty of mechanisms
available to help with that.

What do others think?????????
