The idea behind set_local_path is that it allows running tests
inside subpackages without the need to rebuild the entire package.
set_local_path()/restore_path() are convenient when debugging or
developing a subpackage.
If you are sure that there are no bugs in numpy subpackges
that need such debugging process, then the set_local_path()
restore_path() calls can be removed. (But please do not
remove them from scipy tests files, rebuilding scipy just
takes too much time and debugging subpackages globally would
be too painful).
