The BSDs let you pass path names longer than sizeof(s.sun_path), they read past the end when socklen > sizeof(struct sockaddr_un) up to a limit¹. Let's support that.

¹ I'm 80% sure it's 255 on all BSDs but it certainly is on Darwin and FreeBSD.

Currently we use a pretty naive removal of testing dependencies for SwiftPM by setting an environment variable. We should be able to use Rocket and update our Rakefile script to just remove testing dependencies on each release, and keep it in the development process thanks to that.

The idea came from this PR that I saw RxSwiftCommunity/RxOptional#83, which sounds reall

After discussion with @Lukasa on Discord, it's been shown that the function should not return FileRegion as can be seen from the comments in #975. Hence, just a nit to remove FileRegion from the function docs return type.

It would be useful to be able to toggle/flag into a process-level mode to group by pid and display more process-level information like the full command line.

• For the "Utilization by process name" window, we could group by pid rather than process name so that it's easier to find specific heavy network resource consumers.
• For the "Utilization by connection" window, including the pid + cmdlin

What should happen if deliver_cancel raises an exception? In the current implementation, the shielded cancel scope will prevent it from propagating until the process exits, which might take a while if the crash occurred before signaling the process in any way. Maybe on exception from a user-specified deliver_cancel we should call the default deliver_cancel to kill the process? Or just kill() since

The queue-proxy's main.go file contains a lot of stuff currently and is hard to test. We should decompose the queue-proxy where poss
