In general, I strongly dislike passing file descriptors like this.

If there are reasons that Xend doesn't want to interact with the monitor 
(for instance, if you want to support monitor redirection), we can 
certainly discuss how to enhance the monitor (like having multiple 
monitor instances).  Ultimately, we need to have everyone use the same 
interface to interact with QEMU.
