    with_real_time   ()

Sets sched ahead time to 0 within the block for the current thread. Shorthand for `with_sched_ahead_time 0`.

See `with_sched_ahead_time` for a version of this function which allows you to set the schedule ahead time to any arbitrary value. Note, `with_real_time` will override any value set with `set_sched_ahead_time!` for the current thread.

Introduced in v3.0
