This is by way of a status update, I will do more to tie down what is required to demonstrate the problem as simply as possible. However: root@DEB1-32:~# rsync --archive --progress 10.0.10.30:/var/imap/ /var/imap/ The authenticity of host '10.0.10.30 (10.0.10.30)' can't be established.

The DEB1 UML is now completely dead and locked up, no further messages escaped after this point. If I try to kick it with uml_mconsole: bash-4.1# uml_mconsole DEB1 (DEB1) halt and nothing more happens. 10.0.10.30 is another 32 bit UML. DEB1-32 is the Debian UML, with an IP address of 10.0.10.31. Networking is via mcast. This behaviour is consistent with what I have found all along. I have seen the same on a 32 bit UML running on a genuinely 32 bit machine that is remote to my current location and which I access via the Internet, so the problem arises using real ethernet (via tun-tap) as well as mcast; and in a genuine 32 bit environment. I will try to characterise this more fully, and simplify the method of causing failure as much as possible. I still believe that there is a real problem here, not just me doing something stupid.
