But ofcourse.
Suppose you open an app that is very heavy on memory usage.
Sure enough - almost everything is thrown into the swap - to make space for
Mozilla/JBuilder
Then you close it.
Memory is free again - but the kernel only reads from swap to memory on
need.
So not many pages from swap are called, and the kernel is using the free
space for cache/buffers.
