int | rdlock_count |
int | wrlock_count |
pre-thread part of struct shm_arena that is used to make recursive arena read-write locks. Granted this could use mess data, but since it's not in shared memory it's not memory space critical and may be faster this way, since we don't have to multiple masks and flags. We call it a read-write lock thread attribute (rwlock_attr). Either rdlock_count or wrlock_count will be set, but not both.
