Review Comment:
@gtully I've tried to not be dependent on any timeout. however the current
way this is implemented... a need a page completed before I can move to the
next page.
I will configure the timeout somewhere.

> Syncs are not properly implemented into page files. Basically ever message
> sent and every blob update is issuing a sync update on the context and a
> commit on the Database.
> Certain databases will have an OK performance with lots of commits (e.g.
> Postgres) but I'm not sure how correct is the blob update.
> As part of this task I'm creating a few Database tests to validate these
> changes.
