As it seems to be stable the comment 'Use it with caution...' should be
removed from the config files.

This should never become the default. It works well on one-user, one-disk
desktop machines. The interactive processes are more responsive while
big files are written (taking a CD image for example).

I don't think it runs well on multi-user, multi-disk servers. As I don't
have this class of machines I cannot test it.
