Hmmm.... This occurs when the client tells the server "I want to use
Storable to serialize the requests" but the server wasn't loaded the
Storable module yet.

POE::Filter::Reference looks through the symbol table to see if Storable
is loaded.  If it isn't, it does a require "Storable.pm" .  

Rocco : why is POE::Filter::Reference looking in the symbol table, not in
%INC ?
