/****************************************************************************
 * Name: spawn_execattrs
 *
 * Description:
 *   Set attributes of the new child task after it has been spawned.
 *
 * Input Parameters:
 *
 *   pid - The pid of the new task.
 *   attr - The attributes to use
 *
 * Returned Value:
 *   Errors are not reported by this function.  This is because errors
 *   cannot occur, but ratther that the new task has already been started
 *   so there is no graceful way to handle errors detected in this context
 *   (unless we delete the new task and recover).
 *
 * Assumptions:
 *   That task has been started but has not yet executed because pre-
 *   emption is disabled.
