New issue 1445 by feli...@gmail.com: "script is busy" dialogs may allow
resize/blur handlers to fire
http://code.google.com/p/google-caja/issues/detail?id=1445

'the “A script on this page may be busy...” dialogue box, even if you
choose to let the script continue to run, allows events like resize and
blur to fire and be handled even whilst the script is in the middle of a
busy-loop, except in Opera.'

I don't think handlers firing during an alert() is a problem, but handlers
firing during a "may be busy" might be a problem. can avoid that by
forcing handlers to be deferring with setTimeout.

Deferring handlers will prevent "return false", preventDefault, etc. from
functioning as intended.

So this came up in es-discuss recently. It seems to be an issue only in
Firefox, and Brendan Eich thinks it's a bug in Firefox, so I think there's
nothing we need to do other than keep track of the issue.
