You have a point that this was a judgment call, but note that the last
change to dirhash tuning (maxmem) was also done by me. Since this is
-CURRENT, I will leave this commit in unless it proves detrimental in
the usual testing which goes on.

If you still feel strongly about this, contact me in private and we'll
investigate its effects in more detail.
