--- Comment #6 from Barkdull <jasonbarkdull at yahoo dot com> ---
Is this a bug/deadlock?
Both ptmalloc_lock_all and _int_new_arena try to lock lock_list.
ptmalloc_lock_all also locks all the arenas in the "main_arena" list but
_int_new_arena locks a newly created arena which is not yet in "main_arena".
How can this deadlock?
Thanks
