Anyone who disables compaction should seriously consider switching
to the first-fit allocation policy:

  let () = Gc.set {(Gc.get ()) with Gc.allocation_policy = 1}

This may slow down allocations a bit, but the theory tells us that
it completely prevents unbounded fragmentation of the OCaml heap.
