I have them, I just had books.bin renamed to books.bin.old, and had read-only on
book.bin so I wouldn't blow it away by accident. :-)  Thanks!  (But why does the
bench depend on these being present?  Yuck!)

First block is for Dann's latest 16.8 exe on his site (mt=2):

Total Nodes: 66918014
Raw nodes per second: 264205
C.A.P. ratio: 3.302571
SMP time-to-ply measurement: 3.666667

This is for the non-multiprocessor version:

Total Nodes: 59979081
Raw nodes per second: 166696
C.A.P. ratio: 2.083707
SMP time-to-ply measurement: 5.202899

Especially the last item is a bit puzzling, because this is a single-cpu version
of Crafty.  Dann?

The speedup from 1 to 2 processors on whatever position(s) are searched in
"bench" is 1.585, this sounds pretty low to me...
