Pulsonix warns about any missing connections in the Net Completion Report. I 
avoid islands by adding additional tracks and vias. If a ground trace needs 
to be isolated from the copper pour (I sometimes need that for a crystal 
ground, returning it directly to the MCU ground pin) it will do that, 
automatically, in the latest version. I used to have to put a keep-out area 
round it.
