TIL Mac OS allows multiple processes to simultaneously bind to (listen on) the same local port! So much potential for confusion.

@tim@cloudisland.nz a bunch of OSes will allow that these days providing every process opts in to sharing the port. It’s intended for graceful replacement of a process without dropping incoming requests. (Or multiple cooperating processes, but usually that can be fork or fork/exec.)
