And I just checked, and the old overview implementation also reopens the
files each time.  Hm.  I wonder if this performance problem would be
resolved by just using a cache size of one group for nnrpd rather than
turning off the cache.

(This is, to some degree, an API flaw.  I think it would make more sense
for nnrpd to open the overview for a group on GROUP or LISTGROUP and keep
it open and sitting around somewhere until the user moved to another group
or closed the connection, with nnrpd handling the book-keeping.  But I
suppose using a cache instead keeps the nnrpd logic a bit simpler.)

For the original poster, was this new in INN 2.4-to-be?  What version were
you upgrading from?  (I switched from 1.7.2 to 2.4-to-be, so I don't know
where the problem may have been introduced.)
