// MemoryPurger provides static APIs to purge as much memory as possible from
// all processes. These can be hooked to various signals to try and balance
// memory consumption, speed, page swapping, etc.
//
// This was implemented in an attempt to speed up suspend-to-disk by throwing
// away any cached data that can be recomputed. Memory use will rapidly
// re-expand after this purge is run.
