MPI halo too large w.r.t. core region should trigger a warning?

1

``` from devito import * grid = Grid(shape=(3, 3)) f = TimeFunction(name='f', grid=grid, save=5) eq = Eq(f.forward, f + 1., subdomain=grid.interior) op = Operator(eq) op(time_M=3) ``` will produce wrong values...

Consider: ``` from devito import * from devito.types import _SymbolCache grid = Grid(shape=(4, 4)) f = Function(name='f', grid=grid) f0 = Function(name='f', grid=grid) ``` both `f` and `f0` have the same...
