Agreed. I am actually amazed that the opposite of what is happening
does not happen -- that more people aren't clamoring for this solution.

Six months ago I was testing some TCP application and by accident placed
a sendto() in an infinite loop. The destination of the packets (on my
LAN) locked up completely! And this was a powerful Pentium III with a
3c905 NIC. Not acceptable.
