Hmm. Even with that, I'm not sure. Take the following (untested) program:

(condition-case err1 
    (condition-case err2
        (error "A")
      (error (error "B)))
  (error (message "Oups")))

Suppose I want to capture one backtrace for each of the signals in this 
program.  Assuming I register a debugger that re-throws all errors that it 
receives, won't the second error slip through, due to the nonmacro input event 
counter not having been increased?
