Update.
	* sysdeps/generic/utmp_file.c: Use not-cancelable syscalls all
	over the place.  It would be allowed to have these fucntions as
	cancellation points but the cleanup would be ugly and a lot of
	work.

	* sysdeps/generic/not-cancel.h (fcntl_not_cancel): Define.
	* sysdeps/unix/sysv/linux/not-cancel.h (fcntl_not_cancel): Define.

	* include/fcntl.h (__fcntl_nocancel): Declare.
	* sysdeps/unix/sysv/linux/fcntl.c: New file.
	* sysdeps/unix/sysv/linux/i386/fcntl.c (__libc_fcntl): Only enable
	cancellation if absolutely needed.
	(__fcntl_nocancel): Define.

	* posix/unistd.h (gethostid): Remove __THROW.  Clarify comment.
	* sysdeps/unix/sysv/linux/Makefile (CFLAGS-gethostid.c): Add
	-fexceptions.
	* sysdeps/unix/sysv/linux/gethostid.c (gethostid): Use
	extend_alloca.

	* resolv/res_init.c (__res_nclose): Use close_not_cancel_no_status
	instead of __close.
