+# CONFIG_PRIORITY_INHERITANCE : Set to enable support for priority
+#   inheritance on mutexes and semaphores.
+# CONFIG_SEM_PREALLOCHOLDERS: This setting is only used if priority
+#   inheritance is enabled.  It defines the maximum number of
+#   different threads (minus one) that can take counts on a

+# CONFIG_SEM_NNESTPRIO.  If priority inheritance is enabled,
+#   then this setting is the maximum number of higher priority
+#   threads (minus 1) than can be waiting for another thread
+#   to release a count on a semaphore.  This value may be set
+#   to zero if no more than one thread is expected to wait for
+#   a semaphore.
+# CONFIG_FDCLONE_DISABLE. Disable cloning of all file descriptors
+#   by task_create() when a new task is started.  If set, all
+#   files/drivers will appear to be closed in the new task.
+# CONFIG_FDCLONE_STDIO. Disable cloning of all but the first
