The number of allowed temporaries increases almost with every iteration of an api. We used to support 128, then we started increasing and the newer api's support 4096+. So if we notice that the number of temporaries is larger than our statically allocated storage would allow we just treat them as indexable temporaries and allocate them as an array from the start.
