There did seem to be pretty universal agreement that we'd rather not
use relayfs.

Right - in conversation I had with Mathieu later, he suggested cleaning up
relayfs - I fear this will delay us far too long, and get bogged down.
If we can get one clean circular buffer implementation, then both
relayfs and the tracing could share that common solution,
