Just one more detail to add to the problem reported by Fermin. I've experimented the same behaviour also with a 2.6.7-skas3-v7 host but with a slight difference: in 2.6.7 the zombie process only appears when the console is set to xterm, but not when it is set to a pts. In 2.6.9 the zombie process appears in both cases.
So it seems that the problem should be related to something that changed from 2.6.5 to 2.6.7. I've just made a quick test with a new 2.6.10 guest kernel and the result is the same.
