The intended pattern in the new libxl event universe is to use event
callbacks. So for example for outgoing migration you'd have an fd
writeable event which called into xc. But that's not really doable in
this case because the libxc function is entirely monolithic and
The options for libxl are to fork, or to start a thread.
