I would honestly suggest working on pageforking first.  Once it's merged
you can play with the other stuff.

If page forking is beneficial to more than just tux3, I suggest merging
that first and then working on getting tux3 merged.  Since tux3 depends
on page forking.

I'd have to agree with them that it should be merged separately.

Either that or find a way for tux3 to not depend on page forking.
