Calls libevent’s event_base_new() internally. The backend (kqueue / epoll) is selected by libevent based on the host OS; swift-event does not override this selection.

Traps (via fatalError) if event_base_new() returns NULL, which indicates catastrophic allocation failure. This behavior matches libevent’s own C-side expectations and avoids propagating a try? through every consumer.
