33//     The number of small slots held in the tcache. The higher this number

35//     then small allocations will take longer to complete.

37//     The number of large slots held in the tcache. The higher this number
38//     is, the higher amount of PSS consumed. If this number is set too low
39//     then large allocations will take longer to complete.
40//   ANDROID_LG_TCACHE_MAXCLASS_DEFAULT=XX

42//   ANDROID_LG_CHUNK_DEFAULT=XX
43//     1 << XX is the default chunk size used by the system. Decreasing this
44//     usually decreases the amount of PSS used, but can increase
