+  There are two scenarios where changing the max limit has an effect.  In one,
+  the user is using a .forward and invoking a command of their choice via pipe;
+  for these, we do need the max limit to be 0 unless the admin chooses to
+  permit an increased limit.  In the other, the command is invoked directly by
+  the transport and is under administrator control, thus being able to raise
+  the limit aids in debugging.  So there's no general always-right answer.
+
+  Thus we inhibit core-dumps completely but let individual transports, while
+  still root, re-raise the limits back up to aid debugging.  We make the
+  default be no core-dumps -- few enough people can use core dumps in
+  diagnosis that it's reasonable to make them something that has to be explicitly requested.
