Hi Jeff, can you take a look at this regression, it appears to be on win7 and win8.

FWIW, if it's indeed bug 1092260 and if the the regression is not due to sloppiness of the fix, then IMO it's probably worth this specific regression.

Also we have a 2.58% Win7 Session Restore no Auto Restore regression:

^ note, the bigger regression/fix happened before this landed.  Prior to this push, we had a score of ~743 after the push we have ~753.

the session restore case appears to be on windows 8 as well:

[Jeff Muizelaar [:jrmuizel]]

This regression is believable. That being said I think we're willing to take it so that we get correctness on the machines that this change fixed.

shall we close this as wontfix?

I do not see this on mozilla-beta (probably pgo doesn't exhibit this?), can we close this?
