That would not a correct spinlock use. injection_points_detach() and
injection_points_wakeup_internal() do much more actions than what we
can internally do while holding a spinlock, including both
Postgres-specific calls as well as system calls. strcmp() and
strlcpy() are still OK-ish, even as system calls, as they work
directly on the strings given in input.
