I think you will see with the patch I posted shortly before your mail
that the interaction between libnet and net was actually far more
egregious than just the debug system.  It reloaded everything -
including the case tables (which for some reason don't auto-init and
don't free any existing case table) and the smb.conf file.

But yes, the new code avoids using a magic global variable to prevent
changing the debug level in the smb.conf handling (which then had to be
unset for numerous cases where we really did want to change it).  

This not only makes the API clearer, it ensures that the debug level
value stored in the parameter table is actually the level being used by
the codebase.
