On IRIX and UNICOS (haven't hunted up Solaris yet):
   1. UNICOS Resource quota says your job can have X memory.
   2. IRIX adds you can have H amount of heap memory, S amount of stack

Both allow for overcommitting memory.
   UNICOS hangs with processes in the swap state, and one process that
        can run.
   IRIX does the random process abort.

Both can be controled, I have run IRIX without overcommit, and UNICOS has
been run without overcommit.
