Q2
Can two epoll sets wait for the same file descriptor? If so, are events
reported to both epoll file descriptors?
A2
Yes, and events would be reported to both. However, it is not
recommended.
=========
It's not clear what "not recommended" means. Furthermore, I don't think
there's anything wrong with two epoll file descriptors waiting for different
events on the same file descriptor. One's waiting for POLLIN, the other for
POLLOUT. What's wrong with that?
