Is there a way that we can keep the order of the fields so that anything 
parsing the kernel log for oom kills doesn't break?  The messages printed 
to the kernel log are the only (current) way to determine that the kernel 
killed something so we should be careful not to break anything parsing 
them, and this is a common line to look for.
