Yeah, but these boxes run out of free mem, buffer, cache and swap. On a
machine with 4 gigs ram and 2 gigs swap, something is seriously wrong
when all that ram just disappears, and it isn't just with java apps,
though most of what the developers run are java apps / servers. We've
had a machine with mozilla (no java extension in it) run out of memory
just sitting idle.
