 {{{
 ...
 If the MAGIC_VALUE does not match, or the PADLEN value is greater
 than MAX_PADDING, the party receiving it should wait for a random
 amount of time then close the connection.
 ...
 }}}
 says the spec.

 {{{
 ...
 if (magic != OBFUSCATE_MAGIC_VALUE)
      return -1;
 ...
 }}}
 says the source.

 The spec also doesn't specify the time interval that we should be randomly
 waiting.
