  Death to the "Why should I bother tracking or freeing resources I've
allocated when the OS will do it for me at process termination" school of
programming!


  If anyone is ever again stupid enough to claim "Oh, but it doesn't really
matter", point them at the graphs showing gcc compile-time memory usage
against successive versions, then point them at all the long and agonised
discussions about it in the archive, then ask them if they'd like to be hit
over the head a thousand times with a matchstick or just once with a tree.

  Then hit them over the head a couple of times with a volume of Knuth and
tell them to go away and google 'scalability'.

;)
