But in generic mode the initial thread, or main thread (thread 0), changes between parallel level 0 and 1. we used to use the one for level 1, now the one for level 0. As this is really asking "should I use this thread for initialization" and not "is this the initial thread (in some unspecified level)" I think the name fits.
