Actually "Crafty" doesn't say that.  I call Steven Edward's epd initialization
code and *it* says that.  Crafty has no idea about how many tablebase files
there are if you don't tell it with the egtb=0 command.  That's why I added
that as an option.

However, slowing down by 2x seems to be way too much.  Is your disk light
on when this is happening?  Perhaps Steven has a bug and is trying to open
these non-existant files on each probe...
