 SWAPPED adj. From the use of secondary storage devices to implement
       virtual memory in computer systems. Something which is SWAPPED IN is
       available for immediate use in main memory, and otherwise is SWAPPED
       OUT. Often used metaphorically to refer to people's memories ("I
       read TECO ORDER every few months to keep the information swapped
       in.") or to their own availability ("I'll swap you in as
       soon as I finish looking at this other problem.").
