commit c0f6e06f94dc3b11446bcd773489c570ac545046

    Use EAGAIN instead of ETIMEDOUT on Windows
    
    ETIMEDOUT is not an errno value that would exist in the Windows C
    library. It is just for some random reason defined in pthreads-win32's
    <pthread.h>, which is wrong, and will go away hopefully. EAGAIN is a
    proper errno value also on Windows.
