23299 01478a132908 Just added comments, and cleared some XXX questions, related to int Tim Peters <tim.peters@gmail.com> parents: 23279 diff changeset	19 Since a typical Python program spends much of its time allocating

a6934380c6e7 "Compiling" version Guido van Rossum <guido@python.org> parents: 39 diff changeset	21 Therefore we use a dedicated allocation scheme with a much lower
