Most of the discussion was about MLton-generated executables taking
advantage of multi-core. As to MLton compiles, all you're gonna get
is the codegen stuff we already talked about, and process-level
parallelism is enough for that.

I completely disagree. Whole-program compilation in MLton has never
been about providing rapid turnaround to be the sole development
solution. It's about providing performance and eliminating the costs
of abstraction so that developers can write clean code. All that is
necessary (and which we have achieved) is short enough compile times
that the whole-program compiler can be used frequently enough and
without too much impedance of the overall development process.
One must still have a non-whole-program compiler for development.
Separate compilation is a much better fix for this problem than
parallelized whole-program compilation.
