Seaside and Exupery patch

[Bryce Kampjes]

I've placed Seaside2.8a1-wbk.523 on to the Seaside SqueakSource
repository. This is a patch that moves the serialisation of
contexts from Continuation into ContextPart. This is to allow
Seaside to work with Exupery.

Is it possible to get this merged into the development branch of
Seaside?

Yes, the latest development versions of Exupery will run Seaside, no,
it's not yet practical. Expect bugs and don't expect a performance
improvement yet.

It allows ExuperyContext's to deoptimise themselves before they're
serialised.

Otherwise there's a risk that the code cache is cleared while the
continuation is suspended. If it's then re-instated it'll refer to
machine code that may not be there.

The catch is Seaside stores all the state of a context in a collection
then stuffs it back into the context.

There's no catch. Contexts in continuations will be interpreted but
then they're living from web page to web page so are unlikely to need
to be compiled anyway.
