[gnugo-devel] Slow move

[bump]

Today GNU Go lost on time after taking about 5 minutes to make a 
move in a simple double ko position on NNGS today. The game is

ShaiHulud-gnugo-3.5.3-200401231947.sgf

The slow move is the last one in the file. The game record
has a comment L:5 but I suppose the level is changed after
the move. The move was actually played after the clock ran
out. Up to that point GNU Go was winning in a very good game.

On this machine the move takes 5 minutes. Makeworms alone
takes 68 seconds. 

Bad as that may sound GNU Go 3.4 is even worse on this
move. GNU Go 3.4 took 1781 seconds to generate a move,
spending 675 seconds on Makeworms.
