I have to step in and disagree here - the problem is not that Google teams
don't want to rewrite their apps to work with workers - the problem is that
there are fundamentally things that you *must* do synchronously within the
execution context of a page and SharedWorkers doesn't let you do that.
If you have a mouse click handler and you want to take some sort of
synchronous action (invoke preventDefault(), disable UI, display other UI,
and manipulates DOM elements can't live in a shared worker.
I think that SharedWorkers are a really important tool, and they solve a
bunch of problems, but we should be realists and admit that they don't solve
all of them, and should not characterize the proponents of SharedScript as
somehow just being unwilling to cowboy up and rewrite their apps.
