The memory usage reported here includes all Fortran arrays
(that may be used in application-defined sections of code).
This routine thus provides a more complete picture of memory
usage than <A HREF="../Sys/PetscMallocGetCurrentUsage.html#PetscMallocGetCurrentUsage">PetscMallocGetCurrentUsage</A>() for codes that employ Fortran with
hardwired arrays.
