Hi Jan,
In 2011 the following patch was merged to optimize I/O vs vcpu scheduling:
commit c9f711a5d31e22dac932c1c01e9c0f97caff0988

Poll main loop after I/O events were received
This was back in the days of CONFIG_IOTHREAD. Things have changed
quite a bit since then.
Do you think the last_io/non-blocking trick is still needed today in TCG?
Thanks,
Stefan
