To be fair, a complete rebuild of everything is a relatively huge
task and usually a waste if done routinely.

glibc is never downgraded in any sane system, only upgraded.
The glibc ABI and API hardly ever take anything away, just add new
stuff. Imagine if glibc behaved like boost wrt API changes shudder

So leaving everything else intact after upgrading linux-headers and/or
glibc gives a system that tends to do exactly what it did before and is
in no way broken. Sure, one can rebuild all of world at one's leisure
to take advantage of any new features those packages give, but it is
not *required*

This latest pam nonsense is a very rare event. I really don't feel like
doing massive rebuilds routinely to maybe catch rare events...

 Rgds,
 

Are there actually packages out there that do this? Maybe busybox with
USE=static?

BTW: Another reason for rebuilding (not in this case, but just to be
complete) can be updates in template libraries like dev-libs/boost. Of
course, this cannot happen for things written in plain C, unless we
consider sys-kernel/linux-headers and friends, for example.

See, for example, the problem described in thread

http://archives.gentoo.org/gentoo-user/msg_264b8690e0ab67e3f55c0967cba101ec.xml

from this list last November with glibc-2.14 upgrade, which I also
encountered when upgrading my stable amd64.  Maybe glibc-2.15 has
improved, but I certainly won't risk it when the time comes.  I'd
rather spend (waste?) time to buy that peace of mind, rather than
being locked out of my box.

 So which packages need to be rebuilt? 

none?

if you see segfaults everywhere, rebuild. If apps fail to start, think about 
rebuilding. But until then, why waste the electricity?

 Owing to the initial
 non-availability of the patch file, glibc was the last package I built
 before rebooting. So far I have seen no problems. I can log in as both
 user and root, su works, X and KDE are running OK.
 
 glibc is normally very good at maintaining backward compatibility, using
 versioned symbols.
