Connection read() gives blank output incase device disconnects and reconnects again

[sai bhaskar]

When adding handler to shell() call for adb logcat and device get disconnected then it starts printing empty string.
When we reconnect the device still the output is blank.

I am trying to run shell() in thread.

I went through the code and saw it's done using socket file and i feel socket closes with some error and it's unable to reconnect itself once device is up.

ppadb/connection.py

do we have any solution for this?
