The kqueue based netpoller always registers file descriptors with EVFILT_READ and EVFILT_WRITE. However only EVFILT_READ notification is supported for regular files. On FreeBSD a regular file is always reported as ready for writing, resulting in a busy wait. On Darwin, Dragonfly, NetBSD and OpenBSD, a regular file is reported as ready for both reading and writing only once.
