don't bother with gchar *. Just use char * here. The gchar is
essentially bad idea. We only use it a few rare occasions or when it got
missed in a review.

So here is something we need to talk about. The nettime plugin
infrastructure using a "pseudo" atom. So do we wanna do the same here or
do we wanna change the nettime atom to something simple like this.
I like to have consistency here. Aki, Denis, thoughts?

The sort of general style is to call this user_data.

We also normally don't do double empty lines.

Same here, please use user_data.

And as another general rule, the variable that have an assignment like
the user_data come first.

Same here for the double empty lines. Please fix them all.

This needs to be a == NULL.

Normally we put empty lines on top and below the DBG statement. Just to
make the stand out a bit.
Also in this case we might can remove some of the debug statements once
the code has been tested.
