What a stupid mistake. I’ll fix this in the next version.

When the new option 'irq-eventfd' is turned on, the IO emulation code
signals an eventfd when it want to (de)assert an irq. The main loop
eventfd handler does the actual irq (de)assertion. This paves the way
for iothread support since QEMU's interrupt emulation is not thread
safe.
