Guard desctructor that is not defined when not PETSC_HAVE_PTHREADCLASSES
Note: since the member exists in all circumstances, I suggest always
compiling the PetscThreadsLayout API, but with an empty default
implementation (when not PETSC_HAVE_PTHREADCLASSES).

when F90Array1dCreate() is passed a null pointer for a zero size array it still returns a valid F90 pointer but the F90Array1dAccess() does not return a null pointer hence ISRestoreIndicesF90() and V
when F90Array1dCreate() is passed a null pointer for a zero size array it still returns a valid F90 pointer but the F90Array1dAccess() does not return a null pointer hence ISRestoreIndicesF90() and VecRestoreArrayF90() should not call the restore if the length was zero
Hi,
There seems to be a bug in ISRestoreIndicesF90 when the locally owned portion of the index set is empty. I am attaching a small example illustrating the issue.
