in thread threads::shared variables not really shared... or are they?
The original added 100 1Mbyte strings to @a.
Your example adds 50 * 10 = 500 1Mbyte strings to @a.
Also, each thread will create a 1Mbyte private scalar;
the original only created a single big string.

(The lack of locks is a bit troubling, but the aforementioned global interpretter lock is probably keeping your example out of trouble)
