I wonder if there are any disk suspend systems that are smart enough to tie into the VM system... instead of a specific monolithic RAM-sized suspend file, just flush everything to virtual memory on suspend, and on awake only restore the minimum needed for the OS and accounting, then start swapping everything else in lazily as the user needs it (or in advance in the background if the user is idle)
Given that the disk is several orders of magnitude slower that the RAM, lazily re-loading pages from the disk to the memory can induce very visible and annoying loading delays everywhere (e.g. change tab in browser takes 3 sec).
I'd rather wait 10 extra second than having a slow computer for the next 10 minutes.
