One other comment on is that two places that have a high risk of failing 
is Net.socket due to insufficient file descriptors, and the Net.bind due 
a race with some other entity binding to the same port. Everything else 
is in the noise. In time I hope Apple will fix the macOS bug so that we 
don't need to be concerned with issues like this.
