# These parameters change the way jemalloc works.
#   ANDROID_ALWAYS_PURGE
#     If defined, always purge immediately when a page is purgeable.
#   ANDROID_MAX_ARENAS=XX
#     The total number of arenas will be less than or equal to this number.
#     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.
