On glibc-2.3.2, malloc never tries to align, so a padding of 0 is best.
posix_memalign on the other hand would ideally prefer a value of 4

But testing shows that those 1020 will most of the time be efficiently
used by malloc to place other objects, so a value of 0 is still preferable
unless you have a lot of cons&floats and virtually nothing else. */
