I've tested Tastuhiro's patch on h2c and h2 based connections and confirm it fixes the issue. Thanks!

I understand we are pushing the boundaries of supported functionality a little bit, and I think Tatsuhiro's patch addresses the pragmatic view I gave earlier (serial requests until feature implemented). Our real application wants to provide support for a range of HTTP versions and pipelining options, the library handles that and it removes the need for the application to be changed when a future libcurl update addresses the TODO, we see this as a "big win" and appreciate the efforts to fix the issues we have seen.
