It is your "/fu 0 def"s that are filling up the dictionary.  You see,
def creates a new binding, rather than setting a variable.  What you
should do is create one binding somewhere, and use "/fu 0 store"
instead.  If you want local bindings, do something like:

/fuproc {
  10 dict begin
    /fu 0 def
    /bar (Quux) def
   ...
  end
} def

Which will create a temporary dictionary to hold local bindings.
