multi-tasking within bsp initialisation

[Salman]

Multi-tasking and interrupts are disabled throughout the BSP
initialisation routine.

May I know what would happen if one tries to create a new task within
the BSP initialisation stage.
Would an error code be returned (upon calling rtems_task_create) or
would it be a matter of simply the task would not be scheduled for
execution until multi-tasking is enabled ?

Thanks,

Salman
