Yeah, I figured out what it was used for. And I've successfully updated News and sent it to my Kindle 2 using this process. However, when it's done, it doesn't free up the handles, leaving the system in a somewhat unstable state if another app were to come along that needed lots of handles as well. In order to run "clean", an application really should clean up after itself. Instead, I'm left with 2 open calibre-parallel processes long after they're no longer needed, and they haven't freed up all the handles they used either.
