[computer-go] CGOS (9x9) hangs

I don't know if I caused it or if it just was a coincidence: I killed my bot shortly before a new round would start, re-compiled and re-started it within some 30 seconds. Immediately I receive a 'newgame' and then a 'genmove' genmove b -1195176189379 And now CGOS hangs ... hope this helps.
