+Unix sockets are reliable. If the reader doesn't read, the writer blocks. If the socket is a datagram socket, each write is paired with a read. If the socket is a stream socket, the kernel may buffer some bytes between the writer and the reader, but when the buffer is full, the writer will block. Data is never discarded, except for buffered data if the reader closes the connection before reading the buffer.  ---[Do UNIX Domain Sockets Overflow?](https://unix.stackexchange.com/questions/283323/do-unix-domain-sockets-overflow)
