Got another one this morning. This time the only thing running was the
make index && make readmes, and XFree86.
Actually, they both may have finished by then, I started them up then had
to go to sleep, so I'm not entirely sure how far along it got in the
process. I do know it was past the index and working on the readmes,
though.
