When a listener is temporarily disabled, we start by locking it and then we call .pause callback of the underlying protocol (tcp/unix). For TCP listeners, this is not a problem. But listeners bound on an unix socket are in fact closed instead. So .pause callback relies on unbind_listener function to do its job. Unfortunatly, unbind_listener hold the listener's lock and then call an internal function to unbind it. So, there is a deadlock here. This happens during a reload. To fix the problemn, the function do_unbind_listener, which is lockless, is now exported and is called when a listener bound on an unix socket is temporarily disabled. This patch must be backported in 1.8.
