Yes, I didn't tweak (not twerk) the j's this time. I'm using a laptop and I was having problems with overheating and shutdown if I did -j4. (My AC's old and needs an upgrade (as well as my laptop by the look of it)).

I built Firefox first and then realized I needed xulrunner because I wanted icedtea-web (that's really very silly isn't it - surely it should be possible to make icedtea-web build against Firefox. After all, it's Firefox that's running my Java applets. I didn't want both xulrunner and Firefox on my system if it's not absolutely necessary).

It seems the developers are outpacing the hardware guys, despite Moore's Law.
