The upstream test-suite includes some (8 according to my quick grep) tests for
HTTP pipelining but most of them have never worked reliably enough. 4 tests
are already marked as flaky by upstream. I had to disable another one a week
ago because it was causing random build failures on the Fedora build service:

https://src.fedoraproject.org/cgit/rpms/curl.git/commit/?id=3fb6e235

I tried to debug the test failures several times but have never been able to
figure out whether the bug was in libcurl or whether the failing test-cases
were just verifying something that was not guaranteed to hold.

On top of that, I have been maintaining curl in Fedora and RHEL since 2009
and never seen a single bug report on the HTTP pipelining, which suggests
that not many people actually use curl's pipelining on these distributions.
