Comment 7 for bug 531834

This happened again during yesterday's roll out. According to Tom Haddon, the following DBs had open connections after switching to read only:

hackberry/launchpad_prod_1 and chokecherry/launchpad_prod_2 - we didn't have any to wildcherry/launchpad_prod_3 because we run a script to specifically kill connections we don't want on there (we're considering running it on the other two as well to be sure from now on)
