  games/acm: prevent free()ing unitialized data

  acm may coredump immediately after starting on systems which do not
  zero malloc()ed memory e.g., MALLOC_CONF=junk:true. This is because
  one of the fields of a malloc()ed data structure (w) contains a
  pointer (w->csPool2), and if that pointer is never used, then later
  code will find the pointer is non-NULL and try to free() the memory
  pointed to by the pointer.
