Since my O'Caml is very approximate, I'll answer with a non-answer:
have you tried a purely functional (but asymptotically efficient)
deque ?  Those don't suffer from the length of the queue.

Chris Okasaki has an interesting set of such purely functional data-structures,
with sample code in SML (and/or Haskell) which should be easy to translate to
O'Caml.  Check out, for example
