/* I have several reasons to choose 64 here:
*
* - A cache line must be a power-of-two size.
* - Setting this to anything less than or equal to 32 boosts nothing.
* - I have never seen an architecture that has 128 byte L1 cache line.
* - I know Intel Core and Sparc T4 at least uses 64.
* - I know jemalloc internally has this exact same `#define CACHE_LINE 64`.
