    What cache sizes are you using?  I was using 12M and 2M on a machine with
32M of memory which should be ok.  Depth 14 finished in 1.5 minutes and the time
blew up in depth 15 to 40 minutes.  I will try different hash sizes.
    Meanwhile I escaped with another undeserved draw last night against
brunhilde (another crafty clone) in a similar position.
