Maybe I am not at any qualification to speak design choice of QEMU, but
at least to me, coroutine is really a disaster (Even seems that there
coroutine is nested), I can't even debug a simple bug if involved with
coroutine. This bug is very reproducible and looks to me just a simple
racy problem, but after a long time debugging with it, it just scares me
away without any fruit. In the long run, I think coroutine based
sheepdog block driver will risk maintainability of the code.

Thanks,
Yuan
