Same problem with current CVS version. When compiled in larger
HASHSLOTS then "book add" is much slower - the same way like in 5.05.
Note that runtime changing of hashsize through "hashsize" command or
through "-s" commandline option DOESN'T exhibit this behaviour, only
compiled in default value exposes the problem.

By the way, look at this:

% ./gnuchess-default -s 12345
GNU Chess 5.06
Adjusting HashSize to 8192 slots              <-- adjusting
Transposition table:  Entries=1K Size=40K     <-- but not seen here !?
Pawn hash table: Entries=0K Size=28K
White (1) : hashsize 12345
Adjusting HashSize to 8192 slots
Transposition table:  Entries=8K Size=320K    <-- now it is...
Pawn hash table: Entries=0K Size=28K
