You might or might not want to do that. Dropping caches around suspend
makes the hibernation process itself faster, but the realtime response
of the applications afterwards is worse, as everything touched by user
has to be paged in again.
Right, do you know of a real use-case where people hibernate, then
resume and still care about applications response time right afterwards?
Well if the point of dropping caches is lowering the resume time, then the 
point is rendered moot as soon as you switch to your browser and have to 
wait noticeable amount of time until it starts reacting.
