A PM Application Anchor Block is allocated in the Thread Local Memory Area when a PM application thread creates a message queue. The AAB contains a pointer to the MQ which allows PM to find the MQ in any context. This is particularly useful to the debugger since it also allows the MQ of any PM thread in the system since the TLMA is saved in a thread's TCB.
