What makes it not foreseeable? Apparently only the fact that we have a work-around in place so no one works on it. I can code it up pretty quickly, but I'm flat out of time for testing as I'm going on vacation soon, and hard freeze is pretty close. GPA space is kind of cheap, but wasting it in chunks of 512M seems way too aggressive. -- MST
