[libvirt] [PATCH 01/11] Process all pending I/O for a RPC client before checking EOF

Berrange" <berrange(a)redhat.com&gt; In the socket event handler for the RPC client we must deal with read/write events, before checking for EOF, otherwise we might close the socket before we've read & acted upon the last RPC messages Signed-off-by: Daniel P.
