No problem, happy to help in any way I can. If something useful for the future of TFF came out of that 2 hours of googling, then it was time well spent.

Ah, so you found a useland posix_spawn. Guess I should have looked on OpenGroup more. (I was relying on Google. Probably didn't enter the right phrase.)

Yeah, I wanted to see if I could find a possible solution for posix_spawn for when it will become necessary in some future version of Firefox/TFF. If it's currently fixed why break it again right?

So wait, Mozilla is using OS9-era code in Firefox 5? That's funny and cool.
