Thread-safety has many facettes. An item may be safe in one aspect, e.g. 
not using global variables, but unsafe in other aspects.

Objects (classes) add further topics to the list of items, that make up 
"thread-safety" in general.

During the various discussions I got the impression, that thread-safety 
only can be a headline or keyword, that leads to a detailed description 
of thread-related properties or behaviour of the described item.
