https://stackoverflow.com/questions/36040547/zeromq-how-to-react-on-different-signal-types-on-eintr ZeroMQ may return an EINTR error , but zmq4 does not list it in errors.go. ZeroMQ asks the caller to handle EINTR, so zmq4 should handle it internally or return it to the caller. https://golang.org/doc/go1.14#runtime should have mentioned that not only programs that use packages like syscall <https://golang.org/pkg/syscall/> or golang.org/x/sys/unix <https://godoc.org/golang.org/x/sys/unix> will see more slow system calls fail with EINTR errors, but also programs that use Cgo.
