-   This file demonstrates the high-performance "persistent mode" that may be
-   suitable for fuzzing certain fast and well-behaved libraries, provided that
-   they are stateless or that their internal state can be easily reset
-   across runs.
-
-   To make this work, the library and this shim need to be compiled in LLVM
-   mode using afl-clang-fast (other compiler wrappers will *not* work).
