From my point of view now would be a good time to split. Or, at least, it doesn't look likely to get much better.
The recent yellow dots is due to a test case I added for a type check problem. I can disable that test again if it make things look bad..
I just added some code that should fix that case, it's however likely to trigg problems elsewhere.
Found a few more places that needed fixing, but it starts looking good.
The dots are now turning green again.
So, opinions about splitting?
I'm waiting for the git repository with full backport info. Stephen?
