"Hope it doesn't contain vulnerabilities!"
Which is why I added the caveat. In reality, you don't really have to restart the system even on a fatal flaw. Init isn't terribly insecure with the old version if the exploit was a vulnerability in sockets for instance; whereas if there was a socket bug in libc and you were running Apache, sure as hell you want to reload Apache with the fresh version.
Your average sysadmin (or even your above-average sysadmin) is going to be pretty hard-pressed to figure out which services a given library vulnerability "really" affects. Without really understanding the code, it's hard to say. The only safe thing is to restart everything.
