Well, just my 2 cents... The indexation doesn't need to happen immediately upon boot. Do one directory every minute or so, let the computer start up and do other things while your background task runs. Changes are detected because the operating system notifies dropbox of changes made, they're not continuously scanning the drive. From other comments it sounds like dropbox has registered a hook like that for the entire filesystem, instead of just the working folder. That seems unnecessary.
