	* rt/Makefile (tests): Add tst-clock2.
	* rt/tst-clock2.c: New file.

	[BZ #2978]
	* resolv/gai_notify.c (__gai_notify_only): Copy memory for thread
	function and its parameters and pass it to new thread.
	(__gai_notify): Add support for alternative waiting for completion.
	* resolv/gai_suspend.c (gai_suspend): Add support for alternative
	waiting for completion.
	* resolv/getaddrinfo_a.c: Likewise.
	* resolv/gai_misc.h (struct waitlist): Don't add cond if alternative
	waiting for completion is used.
	* resolv/gai_misc.c: Allow overwriting code to start helper thread.
	* resolv/gai_cancel.c: Include <gai_misc.h> not "gai_misc.h".
	* resolv/gai_error.c: Likewise.
	* resolv/gai_sigqueue.c: Likewise.
