As a matter of interest, when running AFS client on AIX, and
if using memory cache for AFS, does the AFS memory cache
compete with, or complement the way that AIX itself caches
files in memory?
Or to put the question another way, how does AFS memory caching
and AIX file caching interact, if at all?
