A fairly simple change: ccan/io will now call the underlying I/O routines repeatedly until they indicate they are unfinished, *or* fail with EAGAIN. This should make a significant difference to large nodes, which currently spend far too much time calling poll() to discover a single fd is still writable (mainly, for streaming gossip). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Changelog-Changed: connectd: now should use far less CPU on large nodes.
