Using C, you could open the directory, sort the list, compare for a
desired sequence from a starting value to an ending value and pass out a
list of missing files, and it would take only milliseconds, primarily
limited by disk access speed.
Milliseconds aren't so hard to match these days. Let's try my 'compare
to list' shell approach:
# time ls * |comm -13 - ../list

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.
