[Carpet] inefficient recovery from a checkpoint

[Thomas Radke]

Hi Erik,

while debugging a BBH run recovery problem (the run always aborted due 
to excessive memory allocation) I discovered that during recovery each 
processor would iterate through _all_ the checkpoint files to read data 
from, even though the run was restarted on the same number of 
processors. Did something change in the way Carpet (the experimental 
version) sets up the grid structure ? The parameter file I used has

   Carpet::regrid_during_recovery             = no
   IOHDF5::use_grid_structure_from_checkpoint = yes

in it. What's the first parameter setting good for ?
