The cset on which this appeared to start (http://hg.mozilla.org/mozilla-central/rev/ed4a1318e3e9) can't possibly have caused these leaks.

There's lots of fun stuff in the log from around shutdown

I'm not sure which of these looks most suspicious.

Comment 2

[Jonathan Kew [:jfkthame]]

Removed w2k platform from the summary, as this looks like the same leakage happening on OS X. Log shows similar assertions and warnings to those listed in comment #0.

Comment 3

[Josh Matthews [:jdm]]

 This is the same leak that bug 600843 track, right?

Comment 4

[Phil Ringnalda (:philor)]

Comment 2 is - comment 0 and comment 1 are unknowable, since the logs are already gone and there's no way of knowing what part of oth they were in, -chrome or -browser-chrome or "ipc"-plugins or what.
