I still think it's a bug; that's why I wrote the (buggy) patch referred to in the Squid FAQ. See my discussion at http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/kern/uipc_socket.c#rev1.41 (and in particular, the paragraph labelled "The real fix"...) Perhaps someday someone will figure out why X starts acting so funny with this patch and we can put it back, or perhaps someday someone will have time to implement "the real fix".
