There are also alternate cooldown strategies that might help newfs-like
access patterns and wouldn't harm sequential writes, but I don't know
how they'd do with the many-small-files cases. This might be worth
experimenting with, now that I think about it.
i'd like to make it clear that i am was not trying to say that the
behaviour with newfs is a problem, just something i observed. if
it can be mitigated that would be great, but i don't think this is
a problem of any major sort...
