Kind of.
There is one remaining patch,
http://article.gmane.org/gmane.comp.emulators.qemu/205376. Amit says he
sees a problem with it, but I cannot reproduce. But the patch is
obvious and the problem must be latent, so I would apply it anyway.
There is another issue pointed out by Michael Hines with "-serial pty".
I couldn't reproduce it, but I haven't tried very hard.
