Thanks for posting this; it's a good summary, and sound logic.
I think it would be useful to have an even briefer summary in the
code or info pages. Something like:
In a hard real-time system, people don't want different
runs of the compiler to produce code that has different behavior;
minimizing non-determinism is of paramount import. This switch
allows users to reduce non-determinism, possibly at the expense
of inferior optimization.
Would you mind correcting and adding that somewhere?
Thanks!
