Thank you very much for the time you both spent on this issue.
I was suspecting something related to the fact that UDP is a  
disconnected protocol, but didn't thought about a timer problem.  
Running the same loop as Edmund did for more than 700 iterations, I  
only get 100% pass because my Mac is slow enough to get the ICMP  
response :-)

I've commited the change as is, as I can't test for better values.  
However this timeout is only exercised when using one of the network  
mechanisms (tcp, udp, unix, stream) while the default mechanism is  
the native one under Unix and will be the EventLog under Win32. Hence  
this part of the code shouldn't be executed that much. Provided  
people stop using setlogsock().
