 It was me who added the code about "premature end of file" to ftpd(8).
 The code is to be hit only when sendfile(2) reports a EOF condition
 when not all file has been sent according to the byte count.
 That is, the bug should manifest itself in sendfile(2) storing 0 to
 *sbytes and returning 0 when ($filesize - 2^32) bytes have been sent.
 No errno involved.
