When this commit was applied commit 9894dc0cdcc397ee5b26370bc53da6d360a363c2 Author: Daniel P. Berrange <berrange@redhat.com> Date: Tue Jan 19 11:14:29 2016 +0000 char: convert from GIOChannel to QIOChannel The tcp_chr_recv() function was changed to return QIO_CHANNEL_ERR_BLOCK which corresonds to -2. As such the handling for EAGAIN was able to be removed from tcp_chr_read().
