I'm starting to think that.  I just browsed through the code of plruby,
and while I don't know that language at all, there are rb_iterate calls
in places that look like they'd be hard to avoid in typical use.

The fact that the upstream git repo hasn't been touched in nine years
doesn't exactly indicate a lively project, either :-(

If you guys want to pursue this, I'll finish up the back-patch,
but I wonder if we're just wasting our time.
