Ok I took a stab at reproducing the "random pattern."

I have a config file like so:

    $ grep '^Load' local/conf/httpd.conf
    LoadFile /usr/local/lib/libz.so
    LoadFile /usr/lib/libw.so
    LoadModule env_module         libexec/mod_env.so
    LoadModule config_log_module  libexec/mod_log_config.so
    LoadModule access_module      libexec/mod_access.so
    LoadModule setenvif_module    libexec/mod_setenvif.so
    
and I added some fprintf into mod_so at the calls it makes
to load and unload things and then I get this in my
error log.  A quick glance suggests the order is fine.

I have no idea why the handle addresses don't match,
but it's unlikely that is anything other than a typo
on my part.

So... I remain unconvinced.
