// NOTE(Feoramund): By default, FreeBSD will generate SIGPIPE if an EPIPE
// error is raised during the writing of a socket that may be closed.
// This behavior is unlikely to be expected by general users.
//
// There are two workarounds. One is to apply the .NOSIGNAL flag when using
// the `sendto` syscall. However, that would prevent users of this library
// from re-enabling the SIGPIPE-raising functionality, if they really
// wanted it.
//
// So I have disabled it here with this socket option for all sockets.
