UDP packets corrupted under high load

Description
When testing UDP from outside of HelenOS (which runs in QEMU) using the following command:
while true; do echo foo | nc -u localhost 8080; done
some of the packets will arrive with corrupted payload. This can be observed by running:
# netecho -v -p 8080
After some time, netecho will not print "foo" when it receives the packet, but some garbage. The reported size of the payload remains 4 bytes. Sending the UDP datagrams at a slower rate does not exhibit the problem.

Neither I can reproduce this anymore. Looks like the issue is gone or masked. Let's close this as not reproducible.

Can you retest this with latest mainline? I was able to reproduce this with mainline,2119, but not with mainline,2729. It could have been fixed by virtue of new UDP API.
