SGI's Xsgi memory leaks on that IRIX release were particularly noticeable when using it on a 24-bit Indy and viewing lots of porn^Wgraphics. This seemed to be down to Xsgi reserving lots of swap in lieu of a heavy backing store workload, which it didn't actually use. And this often brought Xsgi crashing to a halt anyway. So I would have mixed feelings about adopting such a scheme in future. BMS
