OK, Thanks for the pointers. This is one of the biggest reasons this is an RFC, as I haven't investigated this properly yet. My gut feeling was that this could be on the device model side (i.e. qemu) or even xenconsole handling side - and this was happening on both socket and pty channel types. Anyhow, I can't make the argument/case for inclusion of this patch yet, but being a one-liner I thought of including it for purposes of a working RFC/prototype.
