In addition to this, you might consider setting a RESERVED_MEMORY (or the like,
don't have the manual at hand) of -256M (yes, negative) to allow the job to
run into swap but get a chance to complete.

This leads me to repeat my request for "dynamic resource repartitioning" on 
SMP machines: if there are idle boxen which together would amount for enough
memory etc. it should be possible to temporarily close one of the vms and 
use its resources for the one one(s).
