By repartitioning your drive. You need contiguous space to
increase the existing swap partition, or at least additional
space to add a second swap partition. You can use gpart for
this task. A second swap partition can then be added via an
/etc/fstab entry, for example:

	/dev/ada0p2  none  swap  sw  0  0	# existing 4 GB
	/dev/ada0p7  none  swap  sw  0  0	# added 64 GB

Dynamically you can manage swap space with "swapon" and
"swapoff"; see "man swapctl" for details.
