+* think about when to open new connections
+* requests per seconds only goes up with lower poll timeout in tracker or

 * request parsing:
   * test multiple scrape hashes
   * test with strange/bad inputs, with and without quickcheck

+    let after_path = iter.next()?;
+    let path = buffer[a+1..b] // then add some security checks
+    ```
 * test torrent transfer with real clients
   * test tls
