This avoids creating and revoking Read-Only delegations when only a single client is repeatedly accessing the same set of records.
This also aims to limit the size of the tracking tdb.
Note that writing the copy of the Read-Only record to the TDB database is done by the client, not by ctdbd. This is to avoid a probable need for creating a child process for a likely contended record where locking the record would likely block.
