qmp listen goroutine stuck on send of error forever

[eriknordmark]

Using the example pattern of
monitor.Connect()
defer monitor.Disconnect()
cmd := []byte({ "execute": "query-status" })
raw, _ := monitor.Run(cmd)

even after the Disconnect() has successfully completed and waiting for 10 seconds there is a goroutine stuck forever at
goroutine 20 [chan send]:
github.com/digitalocean/go-qemu/qmp.(*SocketMonitor).listen(0xc00037e300, 0x1c8a020, 0xc00000e070, 0xc000100900, 0xc000100960)
/pillar/vendor/github.com/digitalocean/go-qemu/qmp/socket.go:188 +0x30e
created by github.com/digitalocean/go-qemu/qmp.(*SocketMonitor).Connect
/pillar/vendor/github.com/digitalocean/go-qemu/qmp/socket.go:141 +0x325

That is due to an error as a result of the DIsconnect closing the socket. The Run function is not expecting an error and the channel is unbuffered.

Every Connect, Run, Disconnect results in one more stuck goroutine.
