The comment should perhaps be moved to the allocation? It's really justifying the +1 or mp_maxid + 2 IMO?

No, it needs +2, since bd_subq[mp_maxid] is populated by maxid cpu queue.

I just meant that the comment is explaining why it's +1 (in main now) or +2 (with mark's change) and should go at line 1917
