stdout is by default buffered and a flush is only guaranteed on CR
Sip responses are not CR terminated so we need to ensure autoflush
is switched on so that the filehandle is flushed after a print
Otherwise this can manifest as self checks running slow or
failing due to timeout (although in the log we see the response)
