this is really not currently feasible in RAM.
But that's irrelevant from Snd's point of view -- it normally only
keeps 8K samples (or is it bytes?) in RAM for each open channel
or mix -- are you thinking of some other editor perhaps? One
of my standard "regression tests" operates on a 6 hour stereo
44 khz sound.
Anyway, I looked at the spreadsheet-for-sound business, and I
think I can make it work in Snd without great pain -- you could
use it that way now, but not easily. I'll poke at it further.

This is how virtual memory works. Opening the file with SND causes the
the file's pages to get cached in the page cache. When you close the
file the pages will still be cached. This is so that next time you open
the file, it will not have to be loaded from disk, but from the page
cache.
