Okay, I found the bug goes less severe as soon as kernel 3.13.2, which is to say I bisected kernels from 3.18.0 down only to find this was mostly fixed a long time since. The bug for duplex is more severe in older versions, causing jackd to crash in 3.13.2 while 3.18.0 only has continuous xruns. That tells me they're actually working on it continuously since then; it is actually a major issue for linux audio since it's about having proper usb interfaces for laptops. I've seen quite a lot of work about that from someone called Clemens Ladisch. So I might track down the exact commit that solved it for one-way communication, but I guess the person working on that knows all about it... pretty useless then.
