+The `preload.sh` script can be used for testing with dynamically linked
+executables using glibc or musl:

+It can offer slightly better performance when integrated into the C standard
+library and there are other opportunities for similar hardening within C
+standard library and dynamic linker implementations. For example, a library

+this allocator offers across different size classes. The intention is that this
+will be offered as part of hardened variants of the Bionic and musl C standard
+libraries.
