-/* Future work:
- * - Systems like FreeBSD don't seem to support the IP_TTL option and maybe others.
- * But using IP_HDRINCL and building the IP header by hand might work.
- * - Not all IP options are supported.
- * - Are ICMP handles real handles, i.e. inheritable and all? There might be some
- * more work to do here, including server side stuff with synchronization.
- * - This API should probably be thread safe. Is it really?
- * - Using the winsock functions has not been tested.
