Let's assume that this is so (I'll check).
It's trivially so. If a completion causes an interrupt to be raised,
the vcpu's apic code is executed in the iothread context.
However, that's a bug even with the optimization removed:
iothread vcpu
ioapic interrrupt
apic: set isr
mov $large_value, cr8
on_vcpu(inject)
inject interrupt even though cr8 inhibits it
Setting the isr and injecting the interrupt should be an atomic
operation (easily done be running the apic code on the vcpu thread).
