If your error routines are single-pass, like starting at one end of a
daisychain and each error ripple-passes to the other end, there is no
problem with loopy errors like that. The last error handler could be the
non-replaceable non-preemptable standard Eu error handler, it would simply
report the most recent error it is handed, even if it occurs in a preceeding
user-written error handler.
