yes, its juggling the locations so that both clones can remain active

(yes, it could possibly be even smarter and just start c-Dummy:0 on  
prec370e again but at least both are active unlike the the example  
below which needlessly makes :0 unavailable)

not sure why this is more reasonable... its behaving more like on- 
fail=stop
