We have it here. I've only just got the 6.2 license manager up and running, so
no-one has tested it except me as yet (I need to impose ulimits first).

IDL> bigarr=bindgen(1024,1024,1024,14)
IDL> help,bigarr,/memory
heap memory used: 15033176469, max: 15033176469, gets: 414, frees: 110

It takes a bit of CPU time to initialise 14Gigs of memory...
