Thanks, that explains a lot.  Is this info in the doc's somewhere that I
missed?  Should it be added?(I know with 2.0 on the way it may be moot)

Ahh!! Freshness threshold indeed.  I loosened it up a bit and all is
better.

I'm in a primarily MS shop and our managers want to make sure that any
of the Linux stuff is "easy" to use/manage if any of us *nix guys
disappear, get runover, etc,etc.  (I'm not sure what could be easier to
manage than a text file either.)  Anyway, I'm tryin' to provide some
kinda GUI so these guys can manage it as well.

Thanks for the info.
