FWIW, I added the following TL;DR to the document, which reflects my
understanding of the situation.
Win7 M2 and Mbc tests were OOMing frequently at shutdown because too many
DOM windows were open. This was due to a combination of: (a) multiple badly
written tests, (b) multiple social API leaks, (c) multiple devtool leaks. Bug

will improve our shutdown leak detection. Bug 932900 will (if implemented)
prevent
some of these leaks(?).
Is there anything else we can do to prevent this from happening again?

We should add some checks that hiddenWindow doesn't contain anything unexpected
when closing FF.
The DOM tree and window scope should hopefully look the sama as when starting
FF.
