I understand exactly that and I don't disagree, except in the case where 
it is going to bring down the master (see my further reply). I now 
remember arguing about this a few years ago when we started down the 
sync path.

Anyway, perhaps this is just something of a knob that can be turned. We 
don't have to continue the argument. Thank you for considering what I 
was saying.

Sincerely,

JD
