Well it's all worth reviewing in 7.4.1 - I know there was a bit of a
redesign in 7.3, so maybe they fixed that bit up...
In my 7.2 system I do cloning in 1 hour chunks with a call to nsrstage
-C and a 1 minute sleep in between... Not perfect, but it gets the job
done.
BTW; [RW cloneid] == [RO cloneid] + 1 - if that helps...
cloneid's are actually the unixtime when the clone record was created,
that may be useful to know also.
