Took the patch for a spin.. it seems to behave ok here! No more OOMs.

Quick question: is it to be expected that when I run a calloc(500Mb) on my 
system, when X is up and amarok is streaming live audio, that everything 
(apps) freezes for a few seconds until the calloc task exits?!
The apps probably get pushed out to swap, but I would think that since these 
applications are running, that their pages are kept on the active list?! 
Setting swappiness to 0 doesn't make a difference.

Is there a concept of a minimum working set size of an application? (kind of 
the reverse of an RSS limit)
