Does this really need to be a sync message? It seems like the errors that the
webkit implementation make are mostly misuse type things, and that the benefit
of actually returning the error aren't that big compared the the suckiness of a
sync message.

Hmmm, could there be any issues if the plugin subsequently changes the var? (I
can never remember what order guarantees there are for IPC....)

[brettw, 2011/03/09 17:39:37]

Over the IPC the contents of the var are passed by value so we don't have to
worry about this kind of thing.

Done then. I think.
