It doesn't make any difference unless you're into *very* timing critical
applications, or into very long term applications where a couple instruction
cycles eventually add up to a significant error.  If you run the pic at
20.01mhz instead of 20.00 for an entire day, you'll be off by a total of
about 45 seconds.  After a month that adds up to over 20 minutes...  and
after a year to over 4 hours.  It's starting to sound like my watch...
