Bug#170635: libc6 2.3.1-3 to 2.3.1-5 upgrade breaks

[Magnus Danielson <cfmd@swipnet.se>]

Package: libc6
Version: 2.3.1-5
Severity: critical

On upgrading my Debian/unstable system (oddly called heaven) from libc6 2.3.1-3
to 2.3.1-5 it halts the installation with this text:

Preparing to replace libc6 2.3.1-3 (using .../libc6_2.3.1-5_i386.deb) ...
Unpacking replacement libc6 ...
dpkg: error processing /var/cache/apt/archives/libc6_2.3.1-5_i386.deb (--unpack):
 unable to install new version of `./lib/ld-2.3.1.so': Device or resource busy
dpkg-deb: subprocess paste killed by signal (Broken pipe)
Errors were encountered while processing:
 /var/cache/apt/archives/libc6_2.3.1-5_i386.deb

When the file is to be replaced, it is being used by a heap of different tools.
"lsof | grep ld-" gives a pretty good idea where the trouble is.

This have worked before, new upgrade routines in the libc6 package?

Cheers,
Magnus
