fork() seems hacky now that Ractor exists, and
Process.spawn/popen/system use vfork (along with cloexec being
the default)

Maybe not "JIT", but just-ahead-of-time or on-demand-compiled.
Something like "Proc#compile_to_c" returning an Integer pointer.

It would be generally useful for Fiddle to pass callbacks
implemented in Ruby around, but I agree tricky to get right
because Ruby state could be indeterminate when the C function is
called...

> @byroot I agree, we should at least have `after_fork` (or `at_fork(when, &block)`).

For projects where I'm stuck having to fork, I find "prepare"
(before_fork) just as useful.  I've only used "parent"
(after fork), once, however.

With Ractor, perhaps fork() shouldn't be encouraged/promoted, anymore.

Agreed.
