While they're certainly the correct way of doing this, named pipes don't provide too many benefits under Win32; other than this little problem and having to assign a port number, of course. They're harder to debug, require a whole new slew of I/O boilerplate ontop of your existing files/TCP/UDP sockets, suffer from a bunch of weirdness when connecting, etc.

They're also pretty slow, but that isn't much of a concern here - browsers do suffer from it though (except for Edge, which uses an undocumented IPC API).
