[Isolate-interest] shared heap between isolates?

[Curt Cox]

Please, tell us more of this dubious past.
What is the web browser in question?
Can you provide more implementation details?

I strongly agree that this should be part of the platform.

I think that there is a tendency to view this as a very specialized
feature that would only benefit web browsers.  In reality, many
programs have a need to surrender some gui space to code that
shouldn't really be trusted.  I develop one.  jEdit is another example.
Any program that supports some kind of plug-in would benefit.
