It won't be easy and I'll probably won't have time to do much about it,
for a change... But at least, I'm currently working on fixing locking
on packet filters and actually relaying sent packets so that packet
capture works. Note that this may slightly reduce performance because
of the way filters work, i.e. a net_msg must be completely forged,
with memory copies, before being sent to packet filters, even if there
is no filter installed. If someone wants to work on optimizing this,
feel free to do it, but please mind the details because that's where
the tricky bugs will come from.
