I've written some additional tests (see Seaside-Tests-dkh.102) where I 
poke and prod around the edges and found a potential problem. 
WACurrentContext>>testUnbalancedContextContinuations fails with an error.

I'm just not sure whether the situation exposed in the test will ever 
occur in the wild...as long as the WAContext nesting is balanced (i.e., 
the nesting depth in the continuation matches the nesting depth in the 
'parent' process) things work correctly....
