I did a similar excercise a few weeks ago.  I was able to eliminate
all allocations in my program by compiling with "mlton -inline 100000"
instead of the default.  Maybe that could help in your case as well?

In my program, the allocations that weren't eliminated with default
inlining were just argument tuples for a couple of functions.  The
functions were extremely short and I would have thought they would
have been inlined and the tuples eliminated, but that was not the
case.
