Thanks, I was able to upgrade using the installer. Although I should
mention that the installer still hangs near the end and requires a
force-quit just as it did with 1.9.2 -- I presume because of the rsync
issue. I realize that this is an edge case, but it's not exactly
friendly failure.

As soon as I explicitly told Firefox to reload the page, it came up as
2.0.1. I'm not well-versed enough in browser caching to figure out why
it happened, but I wonder if there's a cache-control headers issue.

Anyway, it's working again, and now this email thread will show up in
Google if anyone else runs into this problem. Thanks.
