[Seaside] Flushing out old sessions,etc..

[Rick Flower]

I used to have an old email that described how to 
get Smalltalk (VW in this case) to cleanup references
to old sessions and whatnot..

I was fiddling with application preferences via 
using a WASystemConfiguration class and everytime
I refresh my Seaside config page I get the 
debugger popping up with references to obsolete 
versions of my configuration class.. I've tried
stopping/starting the Seaside server, doing 
garbage collections,etc.. Nothing is getting 
it unstuck.. Any ideas what I can issue to force
Seaside to clear the old object/session cache?

TIA!!
