It occurs to me that these values are in the audible range for human
hearing.  How cool would it be to have something like "stats -a"
generate an audible version of system stats?!

My load is also close to zero, when just moving the mouse.  If, for
example, I do a "du -a" in an Acme "win" window, the mouse disappears
and/or becomes unusuably slow until Acme finishes.

Acme also hangs for me while retrieving files and directory listings on
/n/sources.  Although the mouse remains responsive during that time,
Acme becomes unresponsive... not even selecting text with the button1
works.

No hablo 8259. ??
