It would not be vulnerable if you would not free the old arena list, right?

Bingo! That occurred to me when I woke up. As I went to sleep, I was picturing an elaborate scheme of saving the "last N" vectors, and recycling them in tricky ways. Overnight, sleep simplified the recycling scheme into an empty statement .

Although I'd declare arenas as volatile...

Why? Thread problems aren't solved by superstition, and that's what adding "volatile" usually is. It's generally no more of a cure than adding a sleep(). More on that in my reply to Guido.
