Hi Juergen,

Thanks for the quick response! tracing through xenstored, looks like
that flag sets the variable dom0_event which is only used in the
xenstored_minios.c as the return value to the xenbus_evtchn() call. I
could naively short circuit xenbus_evtchn() under xenstored_posix.c to
return immediately if dom0_event has been set. If that works, I would
be glad to submit it back upstream if there is interest in
incorporating it.

Thanks again!
Daniel P. Smith
