New issue 2581: heapq.merge is slow in pypy3

Matteo Dell'Amico:

heapq.merge runs definitely slower in pypy3 than in python3. This script:

import heapq
data = [range(10000) for _ in range(100)]

runs on my machine on around 1.2s on pypy3 and 0.6s on python3.

Antonio is a friend of mine and asked me to report this :)
