Summary:                    DEBUG_THREADLOCALS: lock in main/threadstorage.c
must be untracked?
Description: 
I compile asterisk with DEBUG_THREADS, DEBUG_THREADLOCALS, DONT_OPTIMIZE.

When some thread stoped and thread destructor called,
__ast_threadstorage_object_remove hold the lock "&(&tls_objects)->lock" and
tracking information about this lock are placed into thread storage at
function: ast_store_lock_info() from util.c .

So, thread destructor can't remove all "thread-specific data", and call
destructor again and again...

 Conclusively, kernel kill thread with warning:
"Thread 81ea600 has exited with leftover thread-specific data after 4
destructor iterations".

Also, if MALLOC_DEBUG enabled, the "lock_info->thread_name" are
unallocated in this case. And memory debuger report error: "WARNING:
Freeing unused memory at ...."
