+# desciptors by task_create() when a new task is started. If
+# set, all sockets will appear to be closed in the new task.
+# CONFIG_SCHED_WORKQUEUE. Create a dedicated "worker" thread to
+# handle delayed processing from interrupt handlers. This feature
+# is required for some drivers but, if there are not complaints,
+# can be safely disabled. The worker thread also performs
+# garbage collection -- completing any delayed memory deallocations
+# from interrupt handlers. If the worker thread is disabled,
+# then that clean will be performed by the IDLE thread instead
+# (which runs at the lowest of priority and may not be appropriate
+# if memory reclamation is of high priority). If CONFIG_SCHED_WORKQUEUE
+# is enabled, then the following options can also be used:
+# CONFIG_SCHED_WORKPRIORITY - The execution priority of the worker
+# thread. Default: 50
+# CONFIG_SCHED_WORKPERIOD - How often the worker thread checks for
+# work in units of microseconds. Default: 50*1000 (50 MS).
+# CONFIG_SCHED_WORKSTACKSIZE - The stack size allocated for the worker
+# thread. Default: CONFIG_IDLETHREAD_STACKSIZE.
