for those usable to write simple script - there is 
/usr/ports/sysutils/swapd

still - in XXI century disk sizes, even some overcommiting swap space 
doesn't make a problem.

if program needs 10 or more times swap than memory, the program should be 
changed to use less memory hungry algorithm, or be tunable (like sort with 
-S)

swap is NOT memory replacement
