With the wb2uci.eng file that is in the packed it never tell the gui that it
support setting of hash, so it is kind of a bug that the gui offer this to the
user.

If it is allowed to not support hash is another matter: 'which should be
supported by all engines!'

I don't know why this frase is in the text at all, isn't it a performance issue
if the engine use hash or not. Better would be (i think) to set a max memory
usage for the engine. Then the engine-author can use his given memory as best he
can.
