Sara and I just debugged this and our default read timeout is 1 second.
That works well for us, as we only do tiny mysql queries, but is a dumb
default for the wild. I'll update it. For now, you can do

hhvm -v MySQL.ReadTimeout=60000 maintenance/rebuildrecentchanges.php

Or

hhvm -c /var/lib/hiphop/mw/config.hdf maintenance/rebuildrecentchanges.php

Since I added it to the config file.
