758 Most significantly, DownloadThread is responsible for performing the actual downloads as part of the DownloadService's functionality, while UpdateThread is responsible for updating the DownloadInfo whenever the DownloadProvider data changes.
773 Because the DownloadService updates the DownloadInfo objects asynchronously from everything else (it uses a dedicated thread for that purpose), a lot of care has to be taken when upgrading the DownloadInfo object. In fact, only the DownloadService's updateThread function can update that object, and it should be considered read-only to every other bit of code. Even within the updateThread function, some care must be taken to ensure that the DownloadInfos don't get out of sync with the provider.
775 On the other hand, the DownloadService's updateThread function does upgrade the DownloadInfo when it spawns new DownloadThreads (and in a few more circumstances), and when it does that it must also update the DownloadProvider (or risk seeing its DownloadInfo data get overwritten).
777 Because of all that, all code outside of the DowloadService's updateThread must neither read from DownloadProvider nor write to the DownloadInfo objects under any circumstances. The DownloadService's updateFunction is responsible for copying data from the DownloadProvider to the DownloadInfo objects, and must ensure that the DownloadProvider remains in sync with the information it writes into the DownloadInfo objects.
1116 <li> <em>[DownloadService.java]</em> Handle exceptions in the service's UpdateThread - mark that there's no thread left.
1118 <li> <em>[DownloadService.java]</em> At the end of UpdateThread, closing the cursor should be done even if there's an exception. Also log the exception, as we'd be in an inconsistent state.
