/* This function tries to avoid allocations with a total size close to a high
power of two (called the "critical stride" here), by adding a few more bytes
if necssary. This lowers the probability that two arrays differ by a multiple

of the critical stride in their starting address, which in turn lowers the
risk of cache line contention. */
