This kind of approach doesn't really suit GNU Prolog, which is
essentially a native compiler system; you'd be better off producing your
clauses (assertz/1 is ok for this purpose), outputting them to a .pl
file (listing/1 will do), compiling that file separately and building a
new executable, which would then be used as the next "initial state".

Avoid using consult in GNU Prolog; compile (externally) with gplc:
you're likely to see very significant performance gains.
