Weird bug

Somehow the fam events don't propagate correctly when running inside
the webserver.  Running the module in the snot sandbox works fine.

Maybe it runs multiple instances?

rv-invalidate is executed, but something goes wrong.. maybe it's
struct types?

this is weird..
something behind the scenes that kills state or so..

i tried to use a different value for the #rv-invalid tag but that
doesn't work either..  it really is not set in the value that is
accessed by the fam, and set in the other one, so there have to be two

let's protect all RVs with a single semaphore: the one that guards the
whole network update.

Ok, that fixes the problem.  Now can I understand why please??
