On our machine, STOP'd jobs *do* give up their memory if there is
enough demand. Try STOPing the jobs then runa program that does a couple
of big mallocs (use -lmalloc) s.t. the total malloced space > physical memory.

This *always* works for me, the RSS of processes that are ~30,000 pages
drop from ~14,000 pages (16k pages = 64Mb = physical memory) to ~ 50 pages.

This is a 340 running 3.3.2
