I did fix a panic here, but didn't see mconsole hanging.

Not right now.  This requires some thought.  The terminal will only reopen
its host device if nothing has it open inside the UML.  I'm not sure this
is right.  When the host device is closed, UML tells the tty to hang up, 
which causes the session on it to disappear, it gets closed, and UML reopens
the host device the next time something inside UML (normally a getty) opens
that console.

Console 0 is special because it was opened early in boot, so its open count
never goes to zero.

I did this on purpose to make sessions disappear when the host device went
away.  You could argue that the UML session should survive that, and I
think that would be a side-effect of fixing this.
