* It's safe to make direct syscalls to lseek/write here

- * If a write fails we do the same (to cope with disk full)
- * errors.
- *
* Returns -1 on short reads from fromfd (read error)

* Returns number of bytes written to 'tofd'

* return != count then sets errno.
* Returns count if complete success.
