Be bold.  Don't ask, just open PRs if you feel an issue is separate.  Go 
ahead now if you wish.  Having them closed or marked as duplicate is not 
a problem, and it is much easier to track than cluttering an existing PRs.

All these issues with ATLAS will not be visible to somebody looking for 
bug fixes "known to fail" in 4.2.0, because the original problem is now 
fixed in that version, and will soon be in 4.1.1 too.
