Comment (by olau):

 Ken: are you replying to me or the OP? Anyway, I'll answer as if it were
 for me. :)

 A) I don't have a purge in my VCL which as you can see is really simple.
 The stats seem to say that I have one active purge, but I don't know where
 it comes from.[[BR]]
 B) See pmap output below. I don't know what you make of it. :)[[BR]]
 C) The Debian package I'm using is 2.0.4. I compiled it myself to get
 debugging symbols. And I checked the Debian patches, they don't touch the
 source.
