Using top, what other changes do you notice? E.g. does 'buffers'
change? Are there any processes using more swap?
I wonder if hibernating and unhibernating uses swap which the kernel
later leaves 'used' but somehow 'spare' for the next process that needs
swap? Does it eventually free up?
I so rarely swap. However, I occasionally see 4k used. Then again, I
don't hibernate.
