I've just posted http://beta4.com/mc/seaside/Seaside2.5b5-avi.4.mcz , 
which includes a WAComponent>>home method that acts much like 
#clearDelegate.  Note, however, that this may not solve your session 
size problem - I think I've found a memory leak to do with 
continuations in 2.5 that wasn't there in 2.3, that will cause sessions 
to grow much bigger than they ought to.  As far as I know this is the 
last bug that needs fixing before taking 2.5 out of beta, though of 
course I'd love to hear about any others.  It's a nasty one, though, 
and I don't think I'll have time to do anything about it until the 
weekend at best.

BTW, David, anything further to report on your testing framework?  Are 
you using it successfully?
