This is possible.  However I don't want to mount all my file systems 
noatime.  I'm using atime regularly for various purposes, so I don't 
really want to run without it.  Maybe I can try it though.

I think even with atime turned on, a filesystem needs to perform 
acceptable.  I'm not talking about high throughput.  I'm talking about 
xterm+shell taking >10s until the prompt appears, or vim occasionally 
hanging for several seconds.
