Hi folks,

since I follow NetBSD-current (at least kernels) it happens to me that
programs like ps, netstat, top, ... refuse to work after a kernel
upgrade. This is no longer a surprise because these programs use
libkvm to access kernel memory so it has become a habit to also follow
libkvm-current and rebuild it frequently. Normally rebuilding libkvm
(and also doing 'make includes' in /usr/src/sys) makes these kvm
programs work again. 

But since a few weeks the kvm programs don't behave the same. E.g. at
the moment I have a working 'ps' binary that I built from current but
'netstat' (also built from current) refuses to work. The kvm programs
that refuse to work all fail at the point when they call kvm_open() or
kvm_openfiles():

I compared the code of 'ps' and 'netstat'. Both use kvm_openfiles()
with the same parameters. 'ps' works ok but 'netstat' does not.

Can somebody give me a hint why these two programs behave differently
despite using the same code?
