yes, there was partial FMO support in some functions i wrote but it was
never completed.

lack of interrest, lack of anything out there using it and lack of anyone
funding the work probably are the reasons why noone implemented FMO support

Awnsering whenever a program halts or runs forever is
On a turing machine, in general impossible (turings halting problem).
On any real computer, always possible as a real computer has a finite number
of states N, and will either halt in less than N cycles or never halt.
