Comment (by rhaas):

 This turns out to be fairly ugly when done "right" in that Cactus should
 list all parameters that are attempted to be steered but which are non-
 steerable. Cactus uses modes
 (http://en.wikipedia.org/wiki/The_Humane_Interface) to change the
 behaviour of CCTK_ParameterSet, and IOUtil (which provides the utility
 functions for checkpoint/recovery) does not return an error code to its
 caller and itself has not means of asking Cactus what mode it is in (both
 its caller and CCTK_ParameterSet know which mode they are in).

 Attached please find patches to flesh and IOUtil that abort when
 IOUtil_SetAllParameters tries to change a non-steerable parameter. Not
 really my favorite way of implementing this.
