I agree, this would really be a great feature!
Had the same problem, and my solution was not to call curl_multi_perform until
there is new data available. But this is also very unpractical in case of
handling several connections in multi-mode.

My suggestion is: It should be possible to return 0 from readfunction, but
keeping connection alive (NOT cause it to stop the current transfer).
Instead, there should be a spezial return code that signals end-of-file.

Of course, this might bring up some problems with backward compatibility. So,
how about adding a new option that tells curl whether to break on 0-return or
not?
