Yes, I agree. QEMU's command line handling and error messages
often leave a lot to be desired. Unfortunately it's often difficult
to produce good error messages, because by the time execution gets
down to the point where you notice the problem it's a long way
removed from the user's command line options. In this case, the
stdio chardev is a self-contained object which can easily determine
if another instance of it has already been created, but it doesn't
know anything about what that other instance was or what the
code creating that other instance was doing (or even about what
the code creating this instance is doing, though at least in that
case there's the opportunity for propagating an error up to the
caller).
