We only need to ensure that there are no concurrent modifications to the rtld data structures in flight, since the threads that began those modifications will not exist in the child and will therefore be unable to complete them in the child. A shared lock suffices to ensure there are no such concurrent modifications in flight; an exclusive lock is not necessary, and can cause deadlock if fork is executed from a signal handler, which is explicitly allowed by POSIX (and our own sigaction(2) man page) which marks fork as async-signal-safe.
