Well if the point of dropping caches is lowering the resume time, then

Not the resume time - the suspend time. If, say, one has 8Gb of memory
and Linux nicely spreads all over it in caches, you don't want to wait
too long for the suspend image creation.

And nowadays, since you can have 8Gb in a laptop, you really want to
keep that image minimal so that suspend-to-disk is quick.

The penalty of faulting everything back in is a cost we'd be willing to
pay, I guess.

Thanks.
