Summary: HTTP Pipelining, NULL content

Initial Comment:
I have a multi interface, wherein I have put three easy interfaces each pointing to a separate URL. Two of the URLs are to documents with text/html as mime-type and the third is to a audio/mpeg. When I list the returned mime types I get two "text/html" and one "\0", just null. Switching CURLMOPT_PIPELINING to off without changing anything else in the code, and then running, returns two "text/html" and one "audio/mpeg", just like it is supposed to do.

Now I haven't read anything about how http-pipelining works, I don't even know how the client is supposed to separate each respons and tell what request each response corresponds to without using separate connections. I can't see how this is done. Maybe that explains the behavior I see, so it might not be a bug after all.

I will attach a test program for the case.

Also, I quickly just wrote this program to reproduce this case, and I get a segmentation fault in the end when cleaning up. It's probably because I don't clean up properly? I don't know, I don't get the segmentation fault in my other programs.

libcurl version is 7.16.0.

pipelining should have no special/different effect in the view of the app,
it should only make libcurl re-use the connection

I intend to investigate this, but it'll take a little while before I get a
chance
