Regarding patch here:
 http://lists.freebsd.org/pipermail/freebsd-security/2009-December/005369.html


I am trying to patch running systems and find some interesting behavior...

This Process:
 
cd /usr/src/libexec/rtld-elf/
fetch http://people.freebsd.org/~cperciva/rtld.patch
patch < rtld.patch
make
make install
ls -l /libexec/ld-elf.so.1

Causes lots of things to freeze up or crash (example: apache / mysql). 
Restarting those services gets them back online.  :)
For example: /usr/local/etc/rc.d/mysql restart


Now, how do I go about updating /libexec/ld-elf32.so.1  (I am on an
amd64 box, FreeBSD 7.x)?
