 * Notes on Bug 790931 - Unable to remove the Sync account when there are multiple Firefox versions synced
  - Have to consider deleting remote client records as well.
  - Android is supposed to tell installed Apps when an Account is
    deleted.
    - This is the 80-90% case, possibly more.
    - If a user has one App on SD card, presumably they can't afford
      the space for two.  But perhaps they keep one around just in case...
  - In the case of one App on SD card and one on phone, can we always
    guarantee that the phone App is the Authenticator?  If so, we
    could maintain an internal database of
    username/clientID/lastModified, and include lastModified in the
    unpickle request.  Then SD card would not unpickle too aggressively.
  - In the case of two Apps on SD card, we're probably okay: they're
    both on or off at the same time.  If both off, you can't remove
    the Account since it's not present.  If both on, they should both
    receive the Android account deleted message.
  - It is technically possible to access SharedPrefs from two Apps:
    - key word is `createPackageContext`
    - http://stackoverflow.com/questions/6030321/android-retrieving-shared-preferences-of-other-application
    - http://androiddhamu.blogspot.in/2012/03/share-data-across-application-in.html
    - Or a database: http://stackoverflow.com/questions/7053809/share-sqlite-database-between-2-android-apps
    - entails set of Apps knowing a total-order on the members of the
      set of Apps, so that we can always try to write the data as
      robustly as possible.
      - Order of App installation is tricky -- creating a shared DB
        in partitioned space is a lot like Sync...
      - Add/remove App cycles can really mess things up...
    - Could we write a MODE_WORLD_READABLE file in the cache
      directory?
      - No -- there is no shared storage AFAICT
    - I don't think an Android service will help, since we can't
      guarantee any particular service will be running.
