Subject: [Qemu-devel] KVM brokenness due to IO thread changes

Hi,

this is a heads-up, maybe someone has some time to look into this over
the day: I seems like the IO thread changes caused a few regressions to
the KVM mode.

When I keep this feature disabled, I see strange hick-ups of the event
delivery mechanism, and the guest stops once in a while for a second or
so. Attaching strace makes the whole process terminate early (looks like
it triggers a race in the signal handling). And when I enable the IO
thread, I immediately get a deadlock on qemu_global_mutex.

Moreover:

/data/qemu/vl.c:4380: warning: ‘qemu_calculate_timeout’ defined but not used
