/*
* We leave bin-batching disabled by default, with other settings chosen mostly
* empirically; across the test programs I looked at they provided the most bang
* for the buck. With other default settings, these choices for bin batching
* result in them consuming far less memory (even in the worst case) than the
* tcaches themselves, the arena, etc.
* Note that we always try to pop all bins on every arena cache bin lock
* operation, so the typical memory waste is far less than this (and only on
* hot bins, which tend to be large anyways).
