It is worth remembering that MH was written before close-on-exec was
invented ... I suspect that much of what you're seeing is simply a
result of that, rather than anything else in particular.

Using close-on-exec sounds like the right way to me, and if it turns
out that some particular uses require a fd to be passed down (which
usually also requires some arg to tell the child which fd that is)
then those can be fixed when discovered.
