Since this new capability will be applicable to any amount of ram,
it would be handy to have some simple, generic test that would
demonstrate significant usage of zram in any given situation.

For example, I've got 4 Gb of ram, and my normal needs are met by
less than 1.5 Gb having everything available all the time.

Dumbing things down to make-believe I have 512M proves a point,
but not convincingly, to my mind.

Some algorithmic scheme of dd manipulation and Fibonacci series has
an elegant flavor to it, although dd can be dangerous.

Another scheme might be based on spawning several simultaneous virtual systems.
