Hi, we recently ran into this problem in a different scenario where we
manually invoke QEMU and connect to the PTY before starting the machine.
With the existing code, we have to add a one second delay before starting just
to make sure that we capture the early boot message. We are now running a 
patched version of QEMU with pretty much the same change as yours and it seems
to work well. We are very interested in seeing this change, or a variant
thereof merged.
