I wasn't 100% sure what is going on here. I believe glibc is doing this, since
strace isn't reporting the correct values either on RHEL5. syscall.pwrite was
reporting the same values, so I didn't worry about it too much.

I believe I've figured this out. If you add the following line to the test
case, it should work fine:

#define _XOPEN_SOURCE 500                                                       

I'm doing some more testing, but it appears to fix things.
