Issue 160: halts not caught by error handlers
http://code.google.com/p/seaside/issues/detail?id=160

Comment #6 by da... at teleport.com:
I like the idea of #inContextDo: (how about #handleErrorsDuring:?). There  
is a tight
coupling between the ExceptionSet and the exception handlers so making both  
the
responsibility of the error handlers makes mucho sense.

You can avoid the nested #on:do: by using an ExceptionSet, but then inside  
the
handler block you will end up using #isKindOf: or some other type checking  
technique.

I think the rationale basically goes, 'you're in an error handler under  
exceptional
conditions, so efficiency is not a priority' - this is used to justify both  
the use
of #isKindOf: and nested #on:do:).

The good news is that with #inContextDo: the code is inside the error  
handler and we
don't have to provide Seaside protocol.
