Comment 1 for bug 1390472

still need more info - examples/representative databases that we can use to understand what operations are being performed and how progress is failing to be made.

Even if we don't understand how it got into this state, it will help spark new ideas if we understood simply what is the replicator doing if not *getting the databases in-sync*. Even if they're in-sync with the *wrong* information - it seems like they should eventually get themselves to agree on a single version of the truth (even tho it may be lie) - if there's a db that can exist where this doesn't work we should understand why - what information is wrong enough that it can not be fixed?

side-node: as an orthogonal pursuit, additional debug logging lines could be merged to master to help gather information from other people that might be effected by this scenario.
