My guess: this is a "socket buffer size" issue. There should be
two ways around this:
- change the code to have 'ping' set its socket buffer sizes based
on the requested size
- use 'sysctl' to change the system's default send/receive buffer
sizes (see net.inet.raw.maxdgram, net.inet.raw.recvspace).
Naturally, I haven't tried this, or eyeballed the code, so treat
this with some caution.

Justin
