SunOS has had the "swapon" command for several releases which allows
you to dynamically add to the swap space in addition to the reserved
swap partition.  The "swapon" file can be later released when it is
no longer required.  A large swap partition on a disk can only be used
as swap space.  The best recommendation is to size the swap partition
to a reasonable size (usually somewhat larger than the physical memory.)
And use the swapon facility to add to the total swap space available
when needed.
