There are several reasons for this: - MacOS/X doesn't support polling the tap device using kqueue, requiring a workaround to fall back to select(). - On Windows only sockets are properly handled, therefore tinc uses a second thread that does a blocking ReadFile() on the TAP-Win32/64 device. However, this does not mix well with libevent. - Libevent, event just the core, is quite large, and although it is easy to get and install on many platforms, it can be a burden. - Libev is more lightweight and seems technically superior, but it doesn't abstract away all the platform differences (for example, async events are not supported on Windows).
