Logs are not captured (hidden) for passing tests

Part of the current output for cargo test --all:

Since --nocapture was not used, output from tests should have been captured and only shown for failing tests. Capturing is based on a thread-local internal to the Rust standard library. Is logging printed from a different thread than emitted it? Can we find some way to make passing tests less noisy?
