I am not quite sure to follow your argument here. It is still
possible to attach a local injection point with a wait callback that
can be awaken by a different backend:
s1: select injection_points_set_local();
s1: select injection_points_attach('popo', 'wait');
s1: select injection_points_run('popo'); -- waits
s2: select injection_points_wakeup('popo');
s1: -- ready for action.
A detach is not a wakeup.
