Take function new_class(...) in src/object.cpp: this is called during

nothing would be locked.
Maybe this is a more practical example:
void set_foo_attr(object& obj, object& what)
{
api::setattr(obj, "foo", what); // leave cpp in here, no unlock
}
BOOST_PYTHON_MODULE(m)
{
def("set_foo_attr", &set_foo_attr);
}
>>> class X: pass
>>> x = X()
>>> set_foo_attr(x, ['something'])
>>> print x.foo
['something']
Here, enter/exitCPP would be called by invoke.hpp when set_foo_attr
fires, but not when api::setattr calls PyObject_SetAttrString.
