Yes post processing will spike you; but people should not be reporting
"I am VIEWING my collection of 3000 images and the program is using 230M
of RAM" at any point.  You don't need to pull the whole image into
memory until it's viewed; the thumbnails are a few kilobytes in 24-bit
raw pixel format; and you shouldn't try to cache a thumbnail in memory
for every image everywhere.

I didn't argue that something like GIMP shouldn't take loads of RAM.
GIMP I would expect to start around 30ish and then go up steadily, maybe
spike in multiple gigabytes, hit multi-hundred megabytes when it tries
to load a 10mp image, etc.  GIMP is an image editing program, and
post-processing falls into the same category as what GIMP does.

When you say "digital photo management" I think "loading photos into my
photo library, then browsing the library."  If you say "Digital photo
EDITING" I'll start thinking about post-processing and touch-ups.

You're not going to run Ubuntu on a 486; a 486 will likely have 16M of
RAM, my K6-2 had 64M of RAM and everyone else's machines had 32M at the
time.  I was playing 3D games when I had 32M, added 32 more because some
magazine said it was a good idea.

You may have a 266MHz P2 with 256M of RAM.  And no, you're not going to
chew through that either.

photo management/photo editing.  Management is tagging, organizing,
viewing, and storing.
