The callbacks have no way to know if they will be called again, as far
as I know. So the choices are:

1. don't stop the transfer
2. stop the transfer as soon as you've detected that an error has
   occured, potentially failing to read the full response from the
   server, since you can't know if you'll be called again.

What I think is needed is:

3. stop the transfer only once all of the response has been read.

The callbacks, with the current architecture, can't know when that has
occured, as far as I can tell. I think there needs to be a function to tell curl to finish
reading from the remote end (i.e. read until EOF or you block) and
close the connection.
