State-Changed-Why: 
to quote the man page: If timeout is a non-NULL pointer, it specifies
a maximum interval to wait for an event,

The behavior is correct since you wanted to wait for 0 events, and since
it has delivered all the events it can (none), it returns.  Unless provide
with good reason (or maybe a patch to the manpage to document this feature?)
I will close the PR in 5 days.
