Comment(by asn):

 Hm, I couldn't find the root cause after a quick look.

 Philipp noticed that in vanilla Tor, there are two calls to
 `connection_tls_start_handshake()` whereas in obfstor there is only one.

 Also, what's up with
 {{{
 Jul 08 16:30:33.779 [Debug] conn_close_if_marked(): Cleaning up connection
 (fd -1).
 Jul 08 16:30:33.780 [Debug] connection_remove(): removing socket -1 (type
 Directory), n_conns now 5
 Jul 08 16:30:33.780 [Info] connection_free_(): Freeing linked Directory
 connection [client finished] with 0 bytes on inbuf, 0 on outbuf.
 }}}
 right before the idle time starts?

 (socket 9 (that wants to read all the time) seems to be a control
 connection btw)
