This reminds me.
Maybe we want a "memory-hog" keyword for test cases that take up >xM (x 
is debatable) on the current HEAD?
And a "time-hog" keyword for test cases that take up some absurd amount 
of compile time (compared to a previous version or not, debatable)
That way, we can tell where the good cases to profile gcc time and 
memory usage against are, without having to remember what bug numbers 
the cases were attached to?

This would also help when people test patches supposed to fix some time 
or memory issue, to see if it helps on other large cases.
