yeah, since i'm using clamd, there really is no penalty for checking the
parts on their own (and only if they pass the other checks).  if i was
using a non-daemon scanner, i see the benefit of cranking it off in
filter_begin() to prevent the overhead of reading the virus definitions,
etc for each part in filter().  for clamd, the filter_begin() check just
seems to be overhead.

thanks for all the feedback...it helped get my head straight.  ;-)
