As you know, I'm a very strong advocate of this change. I think even if otherports aren't interested in experimenting with this change at the current time,
that we should proceed to experiment with it in Chromium. I would very much
like us to have data about how many sites are impacted, so that we can share
that with others.

We'd like to disallow modal dialogs (i.e., those arising from calls to
alert, confirm, prompt or showModalDialog) during unload events
(beforeunload, unload and pagehide) [1]. Chromium wants to do this
[2]. Since this affects web compatibility, I'd like to get agreement
from the other webkit ports as well.
The benefits are:
+ Fewer annoyances for users who are trying to leave a page.
+ In the case of tab close, allows the browser to hide the tab before
it has finished running the unload or pagehide event handlers (doesn't
apply to beforeunload); gives the impression of better performance.
This doesn't affect returning a non-null value from beforeunload; that
will still cause the browser to show the stay-or-leave dialog. We
think that is sufficient to satisfy legitimate needs to warn the user
about data loss, etc.
Outside webkit, this has been discussed on whatwg, but without a
definite conclusion [3]. Firefox seems to be considering this as well
[4].
All in favour, say aye!
