it seems that we would want to share all the sandbox and single-process code
with all embedders that want to have tests?

[Paweł Hajdan Jr., 2011/09/29 22:55:30]

Not sure yet. I don't want to be speculative, so my plan is to try to unify this
when I get content_browsertests to run (preferably in separate CL for less risky
landing).

[jam, 2011/09/29 23:07:06]

ok sounds good to move this later. you'll definitely want to share this code
though.
