This includes all processes right (extensions, plugins, renderers)?.
browser_processes is a misnomer here. Use some other variable name without
'browser' in it. all_processes?

[dennis_jeffrey, 2011/09/22 18:25:35]

Yes, it includes all processes associated with a browser.  I can see the
confusion in my variable name between "all processes associated with a browser"
and the particular type of process known as the "browser process".  I changed
the variable name as requested here.

No need to repeat this comment

Done.
