Please find attached a patch for aptitude that reworks the locking
logic to keep the frontend lock once acquired and only release the
inner lock; adjusting the manual dpkg --set-selections call as well
to adhere to the protocol of passing DPKG_FRONTEND_LOCKED as needed.

I've done some testing with the remove command in text mode and
curses UI, and it seems to do the right thing, but please do some
more testing.

Thanks!
