I'm really still opposed to the entire concept.  You're proposing to put
a lot of fragile-looking code into a seldom-exercised error path.
I fear bugs will survive a long time in there, and the net effect will be
that we get no information when we need it most.  The numeric printouts
may be ugly, but they are reliable.
