Thanks for the explanation, Neil.  I've currently got something more
or less working with pass-thrus to SRFI-34 exceptions, using a stored
continuation to prevent the exceptions from being re-thrown (as per
SRFI-18, "Primitives and exceptions").

I'm hoping to have something for you guys soon -- I'm starting a new
day job right now, though, so it might be a little while.
