My MVII doenst seem to be swapping much. It just sits there,I presume
compiling away. Everyonce in awhile it hits the FreeBSD server over the net
for some source files,then hits its local disks,and displays another line on
the terminal.It looks like the major bottle neck is the CPU speed,not memory
or disk.(I have 16,and my swap is on a reasonable fast esdi). In any event,I
will hit the 12 hour mark in about an hour and a half.
