So, each number is a completely independent run of Lua?

Then, there is an something interesting: The "distribution of slowness"
is far from smooth.  Several tests are extremely slower in 5.3 than in
5.1/5.2 (by orders of magnitude), and most tests run in around the same
time, but there is not much in between (say, 3~7 times slower).  What do
these tests have in common, different from the others?

Moreover, memory is not always related to time. Some of these tests use
much more memory in 5.3 than in 5.1/5.2, but for many, the difference in
time is much higher than the difference in memory. So, maybe the problem
is not directly related to memory.
