The previous action  to the defrag was to delete 48 hours worth of 
hourly snapshots.  I was wondering if the numerous snapshots were what 
was making defrag so painfully slow.  Not that I know anything about 
btrfs internals, but I suspect that is major enough action to catch out 
any random corruption if there was any.  I think I'll restrict snapshots 
to once or twice a day at most unless that really should cause no issue.
