The worst-case scenario is a denial-of-service which prints a lot
of duplicate pages.  I actually am working on a support call right
now for a file that is crashing a PostScript printer - if we did
the retry-by-default behavior, you'd use up all of your paper
and a lot of toner for errors like that.

Again, there is no way for us to determine the cause of the error
and so we take a conservative approach.

Sometime this fall, and there is no documentation for it yet.
