| * - 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. |
