ok, so just fyi:
	dd if=/bsd bs=65536 count=2
gets truncated on my openbsd development system.

you have to get into this situtation:

	shell writes last block into pipe to sshd process.
	shell dies
	not all data has been read from the pipe.

i can trigger this with
	dd if=/bsd bs=65536 count=2

the figures should be different for other systems, but i think
all systems will show this problem.
