It's single threaded. You can usually stick the context in the request object itself.

  The issue becomes when you're calling some generic library that's unaware that it is running in a request handler. If you want to log from deeper in some logic, maybe you've passed some data or domain objects but not a request/context/session object. Do you pollute that logic with additional data passed in or does your library just create its own logger and call `log.info('intermediate result of some thing: XXX')` and let the CLS magic associate that with the request that generated the call?

    And generally speaking, you want to exit the domain of request/response as early as you can, because it's your interface with the outside world, rather than something that should be pervasive throughout your system.
