[AccessD] Collection limitations

I have always been under the impression that Collections in VBA could hold a
maximum of 32K objects.  The other day I thought someone said it was
actually 65K.  I just tested and got to ~500K before I broke out of the
code.
 
Does anyone know what the real limitation is?  I thought that it had to do
with using an integer to index in of no key was specified but that appears
to not be the case.
