With all these patches it seems weird that we have to drop the lock to
do the sync which will immediately retake it.  It's not broken but it
looks off - it would be better to have a version of _sync() that we can
call within the lock.

Regarding the naming issue that Lars mentioned I think the current
operations are probably fine but calling them _unlocked() meaning they
don't do any locking (as distinct from the existing _locked() which take
locks) might be OK.
