--- Comment #2 from Thomas Hurst <tom at hur.st> ---
The built-in caching doesn't seem useful for this case. Enabling it results in
a test run creating this unfortunate entry in top:
63957 root 9 52 0 24000K 4696K uwait 19 9:15 268.91% nscd
and actually *slows down* stat(1) in my tests - /usr/src goes from 22 seconds
to almost 90, and my CVS repository scan goes from 55 seconds to 2 minutes.
