Comment (by hinder):

 If you recover on a different number of processors, then the messages are
 irrelevant - you already know that the system has to check other files.
 At most, I would think a single message along the lines of "Warning:
 recovering on a different number of processes is often slow" would be all
 you would need.  If you are NOT recovering on a different number of
 processes, then the messages indicate a serious unexpected performance
 problem.  There is the related issue of this happening because of Carpet
 choosing a grid structure at runtime different to what was in the
 checkpoint file (see
 http://cactuscode.org/pipermail/developers/2010-June/005980.html).  I do
 not know if this has been fixed.
