NACK.
Actually this is a workaround for the segfault. I prefer a proper fix.
I haven't understood yet how the event-test causes a segfault here,
but the event-test code itself is broken for multiple added event
handles. In contrast the Python event-test handles multiple added
event handles properly and doesn't trigger this segfault.
