Are you using a lib like GLFW or GLW?  A lot of these libraries create 
threads for you. That maybe where this thread is coming from.

When you set this call back are you able to supply user data with it?  
Good callback API's should do this.  If so you can supply a logger 
instance pointer that way.

You could also use a global logger factor/manager.  Checkout std.idioms
