Sorry, I've tested many different cases, such as these ones

ssh -v -v -v localhost dd if=/usr/local/netscape/netscape bs=1300000 count=10 | ( sleep 5 ; md5sum )

 ssh -v -v -v localhost dd if=/usr/local/netscape/netscape bs=1300000 count=10 | ( sleep 50 ; md5sum )

ssh -v -v -v localhost dd if=/usr/local/netscape/netscape bs=1300000 count=1 | ( md5sum )

and many others and I've never seen this happen. The checksums are always
correct. If you have a specfic test you want me to try, pleae let me know.

Like I said, under Linux at least, by the time shutdown is called, all of
the data has been read in.

You are most welcome to try to show otherwise. I'll give you an account on
a Linux system; please contact me about this. Until then, I will continue
to use my patch; it makes OpenSSH a practical alternative to SSH on Linux
systems.
