Hello,

Thanks Konstantin. I'm trying your patch and that looks better.
poudriere runs since 3 hours now (before the box paniced few minutes
after I start a poudriere bulk)

(I've removed the previous change to panic on the warning "WARNING:
destroying knlist w/ knotes on it!" / I guess it is ok ?)

As far I can see gamin still works (xfce sees changes and the "testgam"
tool works fine : https://people.gnome.org/~veillard/gamin/debug.html)

I will run few "poudriere bulk" tomorrow and report the result here.  

I've tried on my workstation at work which uses the same configuration
as at home, but I was not able to reproduce this problem. The only big
change is that it has 8 GB RAM versus 4 GB here. I don't know what can
trigger this panic.

If you have patch to test or idea, please let me know.
Thanks, regards.
