/* If retention of child status is enable, then suppress it for this task.
* This task may produce many, many children (especially if
* CONFIG_EXAMPLES_OSTEST_LOOPS) and it does not harvest their exit status.
* As a result, the test may fail inappropriately unless retention of
* child exit status is disabled.
*
* So basically, this tests that child status can be disabled, but cannot
* verify that status is retained correctly.
