2.1.10x isnt usable on a server with 16Mb. It eventually fragments
itself to death normally death by dcache fragmentation of main
memory. I suspect a 32Mb box will simply last longer rather than
survive indefinitely.

I'm rebooting 32Mb SMP machines running 2.1.106/2.1.108 every 48
hours to get my compile performance back from 2/3rds of boot
time.

I don't think VM fixing by the ostrich technique is remotely realistic
for 2.2 even if Linus does.
