 * It must tolerate any kind of input (empty, huge, malformed, etc).
 * It must not `exit()` on any input.
 * It may use threads but ideally all threads should be joined at the end of the function.
-* It must be as deterministic as possible. Non-determinism (e.g. random decisions not based on the input byte) will make fuzzing inefficient.
-* It must be fast. Try avoiding cubic or greater complexity.

 * Ideally, it should not modify any global state (although that's not strict).
