Be warned that doing an fseek() on a pipe is not merely useless, it will
confuse stdio and foul up further activity on that file descriptor. The
only safe thing is to use lseek() first with a zero offset to find out
whether it's really useful/safe to seek on that descriptor.
This bug exists in V7, and may appear in x.yBSD or System N; I haven't
checked.
