Just so people won't report the same issues again, a couple of bugs have 
already cropped up (thanks Magnus):

* a backup_label file in the data directory should now not be tarred up 
- we're injecting a different backup_label file there.

* pg_start_backup_callback needs to be updated to just decrement 
forcePageWrites, not reset it to 'false'

* pg_stop_backup() decrements forcePageWrites twice. oops.
