Yes, particularly if we ever manage to convert it to use the new partial
NNTP library in lib, which has an explicit flush and gives you a bit more
control over when you want to send data.  But it might be of benefit even
now.  The only thing that I worry about is that we may lose performance on
XOVER/OVER, where nnrpd does accumulate a large return with a lot of
little writes.  On the other hand, it's through stdio right now, I think,
so it does internal buffering anyway.
