Details are dim memories.  I did this work 8 months ago.

The INN file handle/mmap .IDX caching made it impossible for
a thread to guarantee its cache slot will not be purged by
some other thread ariving later.

I seem to recall also that there was a problem having to manage
potentially simultaneous inserts into a single newsgroup.
