you may want to try upgrading to the host kernel to 2.6.12. Had quite a 
bit of issues with tun devices "hanging" in earlier Linux-2.6 versions, 
but after I switched to a Fedora Core 4 host running Linux-2.6.12 things 
seems much more stable.

My diagnostics at the time indicated some flow control problem within the 
host kernle tun driver, making the driver stall and not deliver packets to 
the application (qemu). Your findings seems to indicate very similar 
result.
