object.data.materials = [ material ]

Theres no way to detect that the NMesh is being created, altered, then 
deallocated (with no change to blenders data)

We cant fix in the current API but in the develoment python API NMesh 
has been removed and this works.

Iv also subtyped lists, so the lists synchronize with blender's data

  ls = object.data.materials
  ls.append(mat)

- works also.
