Yes, Windows pipes are that broken. :(

Using socketpair is a possibly good idea, but I would do it on
libvirtd only.  I don't know exactly how libvirtd uses this pipe, but
perhaps it can be changed to an eventfd-like abstraction that can be
used with both Windows and Unix.  This is similar to Eric's
suggestion, but without the pipe at all.  It would also be a
libvirtd-specific suggestion.
