Hi guys!
I running big process on my machine and the memory pages of some other process been moved to swap.
I run swapoff(8) for clean swap partition and after swapon(8). Ok.
After, i run top(1) and ps(1) to see that the pages were returned. But i
see next:

> last pid: 25743;  load averages:  0.29,  0.21,  0.23                  up

and this:

Swap size == 0 && RSS == 0. Why? Where is my memory page?
