Hmm.  That is a bit too much ad-hoc debug hacking IMHO.  Also I'm not 
sure I like the idea to send debug stuff through chardev instead of just 
writing them to stderr or some logfile.

I do see why you are doing that though.  Unfortunaly qemu has no sane 
debug logging infrastructure.  This is long overdue IMHO, so we don't 
need hacks like this one and also don't reinvent stuff over and over.
