auto-version and shared write-locks

>The VCR should auto-checkin when all write locks have
been removed.

Do you mean all write locks present in the request that
caused the
auto-checkout? Or should we wait till the VCR becomes
completely
write-lock free (i.e, till all shared write locks of other
users are
also removed )?  I would think that a new version of a
resource is
ready when all the members who are collaborating on work on
that
resource are done and remove their shared lock. Unless this
technique
is meant to be used as a backup mechanism for individual
changes made
by users collaborating on the resource through shared locks.
