<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">So what happens if some thread takes longer than 10 seconds to die? Is the allocator still in usable condition after mm_atexit_dump()?</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">The allocator is still usable. That is the purpose of mm_atexit_hash_restore() and the comment where it is called. I found out that mm_atexit_final() can be called before all other threads have terminated. If mm_atexit_hash_restore() does not exist then any thread freeing previously allocated memory would get an unregistered memory warning.</pre>

memory atexit list on
memory atexit list off
memory atexit summary byline
memory atexit summary byfunc
memory atexit summary byfile
memory atexit summary off
* Made check all remaining allocated region blocks atexit for fence violations.
* Increased the allocated region hash table size by about three times. It still isn't large enough considering the number of malloced blocks Asterisk uses.</pre>
