Wow wow wow...

Maybe these netfilter guys you blame had some paid job to do at the time
you sent your bug report ? Or only you have real paid services ?

For the record, I also used NFQUEUE and never hit a single problem.

Maybe I was just lucky, I dont know.

Instead of trying to hide the bug, please be constructive and find a way
to pinpoint the bug, so that we can fix it for good.

A timeout of 20 seconds, on a machine receiving 100.000 packets per
second would not help anyway...
