Crashes in the program following timeout warnings #5
Description
Howdy,
I have been experiencing some crashes in the program following timeout warnings.
see log trace:

Possible race condition between socket timeout (serial_proxy.py:117) and client connect ("/ser2tcp/ser2tcp/server.py", line 57, in _client_connect) both triggered by socket_event.
I am also trying to work out a fix to this, but I am not as experienced with python.
