Thanks Richard for confirming, and testing on Linux. Yes I will file a bug 

It occurred to me that LC shouldn’t be using as much as 34% cpu when it is just 
idling anyway, even when not running a modal stack. Testing just now shows that 
is down to around 16%; of course LC’s time share will depend on lots of OS 
factors and other running apps, but that’s still way too high for an app 
supposedly doing nothing but waiting for events. Turning off the Rinaldi 
revSmartSave plugin brings it down to between 4 and 7%, which is more 
reasonable; presumably something to do with displaying its progress bar, 
perhaps another wait side effect.
