No, running processes continue to use it, but newly started processes will
use the new one (since the inode has changed, and this the dl reference).

Hell NO! :) This does not require a complete reboot. Restarting processes
is the only thing that is needed. libc6 even ensures that init is
reloaded, so it isn't holding the old libc in memory.
