      Description

      The epoll Selector creates the epoll file descriptor with epoll_create, it should change to epoll_create1 as the size specified to epoll_create is ignored. epoll_create1 allows the EPOLL_CLOEXEC flag to be specified so it avoids needing to close the file descriptor when a sub-process is created.
