Pros
- Easier to implement
- More similar to SIGIO in BDS sockets
Cons
- Less information, but this information had a high risk of being
faulty/spurious
Pros
- Simplifies interface
- Easier base implementation
Cons
- May need shutdown functionality, in this case shutdown
can be added as another function in the future
