On platforms that are causing EPIPE at a high frequency this is
resulting in non-working connections, for example when Apple decides to
forcefully close UDP sockets due to an unsoliced packet rejection in the
firewall.
Too frequent rebinds cause a failure to solicit the endpoints triggering
the rebinds, that would normally happen via CallMeMaybe.
