Subject: [PATCH] Error handling for inputs (#316)

SIGHUP is ignored and the program gets into a weird loop waiting for select to happen.
Steps to reproduce:
`go run examples/longmulti.go`
In a different terminat run `kill -s hup (pidof longmulti)` Or simply close the terminal while the program waits for input.
The program is not killed and gets in a weird state slowly killing your CPU
