Yeh - if you aren't using disk cache, you'll be fine.
The alternative is that we modify the OpenAFS cache manager to use an
alternative, but significantly slower, mechanism for opening files in
the cache. This has been done on an experimental basis, but we'd
i still wonder if the cache manager shouldnt open a single file
(sparse
mode) and just seek/read/write. this would solve a couple of
potential
problems with other filesystems as well.
Better still would be using a raw partition, as that would allow you
to get around the memory management rules that don't allow a page to
be moved between filesystems. That would be a large task though...
