Comment(by nickm):
Hm. What I said above about making the change in connection_read_to_buf: I
think that's wrong; we don't want to stop writing every time we get a
wantread: we only want to stop writing in the case you mentioned, where we
try to read because connection_handle_read() failed, and we get a
"wantread". But we don't want to do that in just any case where
read_result <= 0 : only in the case where it actually said wantread.
Also, we need some way to make sure that once the operation eventually
succeeds, we enable writing again, unless there already is such a thing.
