logging is not asynchronous

[zenhob]

Problem: The logging facility uses vanilla ActiveRecord for logging during test runs, which blocks while it does so. This interferes with our ability to maximize concurrent throughput while logging is enabled.

Solution: Use a non-blocking API for logging during test runs.

Workaround: Turn off response logging when running your tests. This is already the default in production, since response logging should only be used when developing tests, not running them.
