Milliseconds aren't so hard to match these days.  Let's try my 'compare 
to list' shell approach:

# time ls * |comm -13 - ../list
5
6

real    0m0.007s
user    0m0.002s
sys     0m0.007s

Note that it is dominated by the system time anyway - although you have 
to wonder about the math there - maybe both processors get counted.
