Sorry, forgot to mention something else.  ensure-writable-dir caused the
build to see these errors.  The patch under consideration -- allowing
the stack to unwind during a throw to `quit' -- also exercised this
case.  I didn't understand it at the time, so I reverted and moved on.
But then the ensure-writable-dir thing brought up the issue again, so
thence the fix, so thence the ability to unwind the stack on a throw to
`quit', even before eval.scm is compiled.

This probably still isn't clear; please ask if you have more questions!
