A good extension to libwrap would be to make it cache contents of /etc/hosts.allow and observe its changes via EVFILT_VNODE kevent(2) filter. And actually reread the file only when its contents change. Of course this implies that application using libwrap is kevent(2)-driven. Sounds like a GSoC project, btw. -- Totus tuus, Glebius.
