I didn't look closely, but I think this will work fine. OSTree caches
the downloaded objects, so it will continue where it left off. Our OS
updater (https://github.com/endlessm/eos-updater/) uses the
GCancellable to stop the pulling.

It's more of a cancel than a pause, though. When you restart, the
progress will be recalculated without any regards to what you did
before. On the other hand, if you're providing static deltas and the
delta download didn't complete, then I believe it starts from scratch
again.
