I'm reminded that D3 has ESTIMATE-COUNT which polls a static
counter in a file control block without searching through the
entire file.  Since the counter is updated by all write
operations it's almost always accurate at the moment of the
request in a dynamic file.  If Universe or Unidata don't have
something similar, and counting is really important, then some
people might want to add this sort of feature via triggers.
