Why would top show the processes are using swap when there is no swap space?

My system has 4GB of RAM so I decided that I don't need to have swap
space.
However, in "top", I can still see that processes's virtual memory is
the
sum of the residential and swap memory. For example:
Swap: 0k total, 0k used, 0k free, 1189192k
cached
PID USER PR NI VIRT RES SWAP SHR S %CPU %MEM TIME+
COMMAND
9580 seki 15 0 2164 1160 1004 856 R 0.3 0.0 0:00.04 top
This is part of the output from "top".
We can confirm that no swap space is used.
However, VIRT=RES+SWAP and SWAP is not zero:
VIRT=2164, RES=1144, SWAP=1020 and 2164=1144+1020
My question is: since there is no space disk, where to swap to pages
to?
Thanks a lot.
