Hmm, it succeeds writing a byte at (off_t)-1? I guess you end up with a
very large sparse file :)

This chunk of the test I blindly copied from test-pread.c and changed to
pwrite instead. It may be ok that this succeeds, it didn't on the 3
systems I tried it on though (FreeBSD, RHEL, HP-UX10), it failed and set
errno to EINVAL.
