// These parameters change the way jemalloc works.

//     The number of arenas will be calculated as 2 * the number of cpus
//     but no larger than XX.
//   ANDROID_TCACHE_NSLOTS_SMALL_MAX=XX
//     The number of small slots held in the tcache. The higher this number
//     is, the higher amount of PSS consumed. If this number is set too low
//     then small allocations will take longer to complete.
//   ANDROID_TCACHE_NSLOTS_LARGE=XX
//     The number of large slots held in the tcache. The higher this number
//     is, the higher amount of PSS consumed. If this number is set too low
//     then large allocations will take longer to complete.
//   ANDROID_LG_TCACHE_MAXCLASS_DEFAULT=XX
//     1 << XX is the maximum sized allocation that will be in the tcache.
//   ANDROID_LG_CHUNK_DEFAULT=XX
//     1 << XX is the default chunk size used by the system. Decreasing this
//     usually decreases the amount of PSS used, but can increase
//     fragmentation.
