 I see, I missed that difference between the code documented in
 TCP/Illustrated and the NetBSD-current sources.  The original code did
 not take the data and datalen parameters, so there was nothing to over-
 write.  In the short term, I suggest reverting the change.  I'll take a
 second look later this evening.
