Comment (by Erik Schnetter):

 Regridding is supposed to happen as follows:
 1. Memory for the new grid structure is allocated
 2. As much as possible, data are copied from the old to the new grid
 3. Where necessary, data are interpolated from the old to the new grid
 4. The old grid structure is freed

 The routine which you list is step 1, allocation. Deallocation is supposed
 to happen in step 4 in a function called {{{recompose_free_old}}}. When
 Cactus terminates, then the memory for the current grid structure is
 deallocated in a function {{{recompose_free}}}.
