Comment (by cypherpunks):

 Could you to test client if tls connection dropped just after client sent
 hello.
 Simplest way to test it with custom fake bridge, using code like this:
 {{{
 #!/usr/bin/env python

 import socket
 import sys


 def create_server(ip,port):
         sock_rc=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
         sock_rc.bind((ip,port))
         sock_rc.listen(10)
         while True:
                 connection,addr_info=sock_rc.accept()
                 data = connection.recv(1)
                 connection.close()

 if __name__=='__main__':
         try:
                 ip="127.0.0.1"
                 port=4433
                 create_server(ip,port)
         except Exception,e:
                 sys.stdout.write('Error on create server\n')
 }}}
 It's reading 1 byte of client hello and then closing socket, triggering
 rst packet.
 Add to torrc file:
 {{{
 UseBridges 1
 Bridge 127.0.0.1:4433
 }}}
 Interesting to know what openssl reports
 ("connection_tls_continue_handshake():" line of logs) with such bridge for
 your case.
