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.
