Good work!

Okay, I wrote such a test. It fails with Jack's ringbuffer (jack1 r3004) but
succeeds with Portaudio's one (r1240).

I meant Test First, not putting a memory barrier between us and past bugs ;)
My concern is: people around say memory barriers are missing, but could anyone
write a unit test that actually turns this assumption into a bug? I'm no memory barrier expert, but from what I
read this looks like a complex
topic. Adding them to jack's ring buffer may be hazardous without carefully
crafted test cases. Bugs related to missing barriers may or may not happen
according to various hardware-related issues.
the point of memory barriers is
really to remove the need for test
cases :)
