The iterator over registered callbacks failed to account for the possibility that the callback would remove itself from the list. If this occurred any remaining callbacks would no longer be reachable from the node. Switch to the slist iterator that is safe for self-removal. Note that the slist API remains unsafe for removal of subsequent nodes. Even with the corrected code removal of the next callback registration (cached in tmp) will result in it being called anyway, with the remaining unremoved registrations not being called. If the next callback were removed and re-registered on a different device, the callbacks would be invoked for the wrong device. Resolve this by a documentation change describing the conditions under which a change to callback registration from within a callback are permitted. Add a similar note regarding the effect of adding a callback. The current event invocation behavior for callbacks added within an event is explicitly left unspecified, though in the current slist implementation newly added callbacks will not be invoked until the next event.
