I would like some way to save certain positions that arise during the >search, e.g. positions that cause null-move failures. It could produce garbage, since this could be done while other processors are still searching. On a one cpu machine, it could still produce illegal positions since they are common in the q-search in wild positions. In short, no telling what you will get out. On a multi-headed machine, possibly a position that could not possibly occur, or just an illegal position as happened in the above case if you don't have more than one cpu. Some of this is fixable, and I have added it to my to do list, but for the current version, it will screw up.
