        Hi,

        I have been using 2.3S1 on a Sparc running Solaris 7 with
around 25GB of cache. If I recompile using --enable async-io
and then change cache_dir ufs /xxx aaaa bb ccc to
cache_dir asyncufs /xxx aaaa bbb ccc will it continue to work
or do I need to purge all the cached objects. TIA
