Comment #3 on issue 1492 by kpreid.switchb.org: caja.js needs a way to kill
guests
http://code.google.com/p/google-caja/issues/detail?id=1492
As Doug Koellmer points out today on google-caja-discuss,
https://groups.google.com/d/msg/google-caja-discuss/Tn_H7-Y_-A0/EaMqQmZAxkIJ
Domado should be extended to cancel (or suppress the callback of)
outstanding setTimeout, setInterval, and XHR to help clear out an
unaware/uncaring guest.
We should also make sure make sure that a “dead” guest's remaining
authority is revoked or harmless even if we think there is no way for the
guest to execute further. (For example, if guests can still compute and the
vdoc-container___ element was reused for another guest (not something we
would actually do), the first guest could modify it.)
