> currently, external changes (i.e. changes committed by other sessions) are silently merged
with transient changes. this might potentially cause concurrency issues/inconsistent transient
state (see e.g. JCR-2632).
> it would probably be better to isolate transient changes from external changes until
they're saved (true copy-on-write).
