-DESCRIPTION
-This module tests four basic scenarios with the usage of the following LIFO
-routines:
-
-   nano_isr_lifo_get, nano_isr_lifo_put
-   nano_fiber_lifo_get, nano_fiber_lifo_get_wait, nano_fiber_lifo_put
-   nano_task_lifo_get, nano_task_lifo_get_wait, nano_task_lifo_put
-   nano_fiber_lifo_take_wait_timeout, nano_task_lifo_take_wait_timeout
-
-Scenario #1
-  Getting (and waiting for an object) from an empty LIFO.  Both fibers and
-tasks can wait on a LIFO, but an ISR can not.
-
-Scenario #2
-  Getting objects from a non-empty LIFO.  Fibers, tasks and ISRs are all
-allowed to get an object from a non-empty LIFO.
-
-Scenario #3:
-   Multiple fibers pend on the same LIFO.
-
-Scenario #4:
-   Timeout scenarios with multiple LIFOs and fibers.
-
-These scenarios will be tested using a combinations of tasks, fibers and ISRs.
