Use non-blocking writes for clients We may have console clients that are remote, and so the write() to those clients may block. Since we're single-threaded, that block will delay output to all other clients (and read from the UART). This change uses nonblocking IO for the client sockets, and a small buffer to handle writes that would have blocked. Signed-off-by: Jeremy Kerr <jk@ozlabs.org>
