I didn't even know it's not only ugly but also *that* slow :-)

I only know that the private networking headers have some sysctl-stuff 
in them. I would rather see it go away, though, and have a network 
specific configuration method via ioctl()s only.
Also note that BeOS BONE does not have sysctl. If you ask me, I would 
like to put the whole network into a BeOS-like shape with useful 
defaults and none of the usual config files left (/etc/protocols, /etc/
networks, /etc/services, ...).
I would like to have an application called net_server (or 
network_server) that brings up the networking stack, configures it, and 
then plays the role of inetd - with configuration via BMessages that 
are done immediately without the need for a restart (of that server).

pselect() is exported from libbind.so under BONE, but maybe it's not in 
R5, and that's why Waldemar removed it - since he missed the 
opportunity to write down his reasoning, all we can do now is publish 
it again and see where it breaks :-)

I think the DEVNOTES approach as is, is not very useful - the status 
quo should be retrieved from the source files anyway (as such docs are 
always out of date). If you don't write your reasonings into commit 
messages, I think that what's belong there: a short overview over the 
different targets (userland vs. kernel), and reasons on why things have 
been done the way they are.
