I have a feeling that patch may get some discussion upstream. I was
going to say that the version we're working with is simpler and easier
to work with until upstream decide what the right approach is. Victor
as already pointed out that even then I messed it up slightly!

I certainly appreciate getting something upstream and that is the right
thing to do, I think a simpler workaround for us is fine until that
gets sorted out though.

I'm particularly conscious that we've not built M3 yet and that Bruce
has limited availability due to travel so we have a few constraints
here.

Cheers,

Richard
