This logging is all done at initilization, before we start a GC so I 
don't think there is a point in adding the GC id decoration.

There are some internal table for such conversion. I can look in to 
adding it there. For the public documentation we have selected a subset 
of all flags to document. I don't think this flag is used widely enough 
to qualify for that list.
