Would it be worthwhile having the kernel auto-detect how much RAM was
available, with something along the lines of the following pseudocode:

Determine RamTop.
if (RamTop >= 1000 Meg) {
if (RamTop >= 2000 Meg) {
if (RamTop > 3000 Meg) {
Warn "Limiting RAM usage to 3,000 Megs."
RamTop = 3000 Meg
}
Configure for up to 3,000 Meg of VM.
} else {
Configure for up to 2,000 Meg of VM.
}
} else {
Configure as currently.
}

No, I'm not the person to do this: (a) I haven't any means of testing
anything I do along those lines - I only have 128 Megs of RAM anyway,
and (b) I don't have the time anyway...

Best wishes from Riley.
