But events are actually available on the second one?  This sounds like
a bug somewhere.  Could you show the code?

Yes.  This might be a good idea in any case so that in case of a logic
error, you can detect this immediately when you get -EAGAIN instead of
having the select call hang.

poll(), but it won't behave differently.
