43 /* */
44 /* This function doesn't do anything and is simply used to indicate */

46 /* as a result of the cleanup routine being called from timeout */
47 /* processing, which takes place in the system timer thread or in an */
48 /* ISR context - neither of which can obtain the IP mutex protection */
49 /* and thus needs to be deferred. */
