...with a modification to support running more than one, I presume?

I'm fine with that (if you can show me how this is supposed to work), although personally I think having to register a pass just to store this data seems...kind of weird?  Maybe there is a good reason to do it that way as opposed to with the explicit callback objects as in the commit message here.
