Bug with controlling_process for Connection

[klacke]

To reproduce, run

cd  test/example
make all
lux p_connect.lux

[qzhuyan]

relates to #169 ?

[qzhuyan]

I got this:\

- Stream
+  {stream, 1}.
+ Failed to start_stream {error,stm_open_error,invalid_state}
+ --> 

Is this the same error you get? I just want to make sure we are checking the same trouble.

[klacke]

Yes, same error, and no, not related AFAIK to #169

[qzhuyan]

looks like a monitoring issue,
add
timer:sleep(1000) solved the issue.

The connection is closed because the old owner is dead. I will check if it demon the old owner pid while swap the new owner.

solution: #172

[qzhuyan]

test pass after merge.
