This is essentially a non-problem with C News.  For one thing, all nonlocal
articles go via input spooling; for another, incoming news can be processed
during expire runs.  (Incoming processing only *appends* to the history file,
so it is not necessary to lock said file until expire hits EOF -- then, and
only then, C News expire acquires a lock on the file and checks to see if
any more has arrived.  This reduces the lockup time to a few seconds.)
