I've just checked in a change which should fix this.  You are right in that
Osmosis was limiting the maximum number of nodes in a way to 2^15.  This
has been increased to 2^31.  It adds a small overhead to Osmosis
processing, but should be barely noticeable.

This change will be available in the next development build.
