Looking at the stats now, I don't really see that vmdev needed more
memory than it had - I suspect that whatever caused it to fail that
day would still cause it to fail with 2gb RAM as it must have gone off
the deep end at that time.

Baron could benefit from having a little extra cache room, however...
perhaps we should reduce vmdev's memory back down to 1.5gb?
