That just moved the error to another file: audio_v.pig, which would precede avatarstatic.pig if I hadn't pulled avatarstatic to the front.

It looks like I'm hitting some kind of cumulative size limit. But all the totals I've checked come to weird totals, often smack between 2^29 and 2^30. I would not be surprised to see something nearer to a common bit boundary like 2^32. The numbers I am seeing just don't shout "here I am, I'm the problem."

I'm going to try fiddling with the volume size and the way we collect files to be packed and see if that makes any difference.
