------- Comment #4 from Laurent Glayal  2007-10-18 09:23 UTC -------
On an udp connected socket the ICMP messages are not frequent (not enough ICMP
errors as packets sent (don't know really why...but it's quite a good thing)),
so iterations around select() call are restricted.

It's quite difficult to detect errors using select, code could switch to
poll().
Using poll() errors on file descriptor (shutdown/close on fd would be detected
by poll), but errors from network (like ICMP messages) are only detected by
next system call (such as read/recv). 

I see no easy way to handle errors as the file descriptor is full duplex and
not only used for receiving.
