Yes, we should remove those lines. I suggest to use debug() for here, so that 
they are printed when DEBUG is defined.

No, I didn't test this. IIRC there is still a TODO in the source that this 
still has to be implemented/tested. It shouldn't be that hard though. I would 
really appreciate it if you (or somebody else) could take a look at this.

Thanks.

BTW: I'm not available today.
