Many of the libc functions have to repect the same rules as the kernel
and the kernel implementations may also fail, see bug 6489267 where
strncat() from the kernel caused a panic because of accessing a byte
bejond the permitted range.
The difference is that we _exspect_ that the kernel implementation have been
coded carefully enough to avoid a e.g. kernel panic but the same bug in libc
would cause a core dump under similar conditions.
Of course all functions from libc that use malloc() or for other reasons
may need a lot of memory are in a different game.
