 When adjusting these variables, be aware that:
- - there is unlikely to be a good use case for setting wait_time higher
-   than stampede_semaphore;
  - wait_time * wait_limit is designed to default to a number less than
    standard web server timeouts (i.e. 15 seconds vs. apache's default of
    30 seconds).
