Tomcat: do we leak just when flashgot is installed, or anytime afterwards when it is installed too?

Comment 3

[David Baron :dbaron:]

Is this just a shutdown leak, or does it increase when you use more browser windows?  (Probably easier to tell with leak-gauge logs, which will also tell you which windows leaked -- e.g., if it was the about:blank hidden window.)

If it's a shutdown leak, bug 398219 might help here.

+ing since Flashgot is a pretty common extension.  If this is just a shutdown leak we should minus

This looks like it could be a shutdown leak. Tomcat, it would be great if you could whack at this a bit more and see if you can get it to leak more than 2 nsGlobalWindow
