It went to a point where gdm got killed - (and it and then I lost
control of the console screen)

I don't notice the GB usage directly. However when processes get
killed - my 'top' command freezes - and doesn't get updated. So there
could be a single malloc which consumes that memory.

I'm more puzzled by linux behavior - instead of killing yum for
requesting that much memory - it looks for other processes to kill.
