------------------------------------------------------------------+---------
 The "threshold for uploading new stuff" bbackupd artificial block check
 requires bbstored to maintain at least soft-limit plus 1/3 of soft/hard
 limit delta to attempt a backup, regardless of the (potentially smaller)
 new backup size. If the soft limit is set low (to retain few old/deleted
 blocks) or set to zero (to discard all old/deleted blocks on every
 housekeeping run), this check causes bbackupd to abandon a backup, even
 though there might be plenty of free blocks on a server. Attached patch
 changes the check in question to investigate a hard limit only.
