Yeah, cutting the sentence that way evidently did not work out, sorry. For posterity: > This cursor unfortunately cannot be stored in userspace without complex coordination, since POSIX allows file descriptors to be shared by an arbitrary number of processes, after e.g. forks or SCM_RIGHTS transfers (even though this use case is most likely very rare, so it’s not entirely impossible for this state to be moved to userspace).
