Good idea or too implementation/internals-dependent?
We can note it is implementation-dependent behavior in the manpage.
I can prepare patches based on existing NEWS-* files.
Work-in-progress here with *_STACK_SIZE.
I added a header section hopefully clarifying the difference between
VM vs. machine stack size changes.
This manpage feels a bit long, I think the FEATURES section should be moved to a
new ruby(7) manpage. Perhaps these new tuning variables should also be
moved to a ruby_tuning(7) variable for longer explanations
