What I recommend won't hurt and can certainly help flush older shared
libraries out of memory.

The point is probably that in the Debian packages, the maintainer scripts take
care of the necessary steps, so the user doesn't have to.

This always got me tho...  If a program is already running, how do you
make it stop using the old libraries?  If 'restarting' /sbin/init makes it
reload, I'll take your word at it.  But what about all of the other apps that
happen to be running?  The bash session I happen to be doing this upgrade
from.  Or X (yes, in an ideal world, you goto single user to do this
anyhow.. :))

They keep running with the old libc.  No big deal, really :)  The RAM
will basically not be reclaimed until after you reboot.

That's sorta what I figured.  So on debian certain services get restarted
so that new children are sane, yes?
