+
+	Disconnect stale clients.
+	* doc/lyskomd.texi (Parameters): Document "Stale timeout".
+	* src/server/server-config.c (parameters): Added "Stale timeout".
+	* src/server/ramkomd.c (server_init): Configure the stale timeout
+	of ISC.
+	* src/server/param.h (struct kom_par): Added stale_timeout.
+	* src/server/connections.c (stale_cb): New static function.
+	(login_request): Pass stale_cb to isc_set_read_callback().
+	(setup_timer): Moved to timeval-util.h, and added a return value.
+	All callers updated to check it.
+	* src/server/testsuite/lyskomd.0/38.exp: Set the "Stale timeout"
+	to 10 seconds, so that we can test disconnection of a stalled
+	client in a reasonable time.  Don't expect that test to fail.
+	* src/server/testsuite/get-time-often.c (abort_pending): New
+	static variable.
+	(do_write_only): Now global static, not a local variable in main.
+	(setup_timer): Removed.  Use the one from libmisc instead.
+	(write_server): Handle ECONNRESET, EPIPE and end-of-file when only
+	writing.
+	(arm_timer): Check return value of setup_timer.
+	(end_it): Clear abort_pending.
+	(main): Set abort_pending if we are about to abort.  Cancel the
+	timer if the top loop returns before the abort timer fires.
+	Treat ECONNRESET the same way as EPIPE.
+
+	Moved setup_timer() to libmisc.
+	* src/server/connections.h: (setup_timer): Moved to
+	timeval-util.h, and added a return value.  All callers updated to
+	check it.
+	* src/libraries/libmisc/timeval-util.h,
+	src/libraries/libmisc/timeval-util.c (setup_timer): New function.
+	* src/libraries/libmisc/Makefile.am (AM_CPPFLAGS): Search liboop.
+	* src/server/text-garb.c (garb_callback): Check return value of
+	setup_timer.
