Mr. Zachary Pincus had pointed out this problem(2002/09/10). And 
Hideki KAWAI-san had pointed out this, too(2002/10/26).  Their 
contents of indication are almost the same.  I also checked the 
problem.

In response, Tetsuo Suzuki-san taught us the solution today.

The above patch is created according to his directions. As a result 
of my investigating, I think that the udp problem is repaired by the
patch.

Please merge this patch, Greg.

Thanks.
