When doing a staggered build, when it gets up to Building HTML Pages: Building Categories: Page x out of y

As it goes through pages 1 to y, each time it just generates all the pages.

This looks like a bug, as should staggered build, just build 5 pages, then reload the page and go onto the next 5, not build all the pages, then rebuild all the pages y number of times.

Also if it is intended to work like this, its stupid because, it will just timeout before it finishes building the links.
