Sure, I agree.

We've been talking for quite some time about making openchange an external
process that e.g. registers its DCE/RPC interfaces with endpoint mapper and
just listens on its own ports. However, that is a non-trivial task and it has
taken a backburner to higher-priority work in OpenChange.

This change (removing DEBUG) breaks OpenChange as it works at the moment, and
will make it impossible for it to work with Samba 4.2. These APIs shouldn't be set
in stone, but let's change Samba in conjunction with OpenChange.
