Merge branch 'zecke/changes/paging-order'

Various paging clean-ups. I couldn't re-produce the assert that
was hit by Rhizomatica in the subscriber code. Let's clean things
up a bit to avoid some of the potential issues this code had.

Always stop paging regardless of where the subscriber is at the
time of the cancellation.
