Yep, i can see that now. Didn't think to look inside rte_member_free()
:/ However, you're creating a race condition there - you're unlocking a
tailq, and then locking (and unlocking) it again inside
rte_member_free() - it probably needs _thread_unsafe() functions that
you can call from behind the lock.
