Oh my goodness no. I avoid X whenever possible. This is on a Real Manly Operating System - RISC OS! No virtual memory to rescue you from excessive holding on to unneeded objects.

PacMan ran all on its own overnight so I don't think routine operations there are causing any problems but as soon as I started scrolling around the Scratch scripts pane things got nasty. Of course, it's such fun debugging this stuff with the morphic stepping and the halt not neccessarily stopping the right process and so on.
