Comment:

 What would be needed to make this happen?  It could improve performance on
 architectures with a large vector size, as long as the memory allocation
 takes note of the ghost size, and aligns the first //evolved// point to
 the vector size.  I seem to remember that unaligned memory access on Intel
 systems is fairly fast, so maybe the benefit of padding applies to non-
 Intel systems only, in which case this enhancement might be less
 interesting?
