I realize this is now ancient history, but you really should have called it
something else then.  uint32_t is defined to be 32 bits in ISO C, and so it's
amazingly confusing for newcomers like me!

I know you guys love libreplace, but there are some lines you just can't
sanely cross, like replacing pread and pwrite with seek & read/write.  You've
complained about glibc doing similar to pselect, IIRC :)

I *did* actually write a test program to make sure I wasn't missing some
horrible subtlety.  Esp. when I saw you were the original author :)

Thanks!
Rusty.
