Fixed connection lost of debugging sessions. (#2636)

Browse Source 
The peek of the socket does not work on other platforms,
beacause the errno is not set correctly. The code path
added by #2427 Linux specific, so it has been guarded
to solve connection lost issues during debugging sessions
when the client does not send data but still connected.
