Such overlappings are often (if not always) found by the refcount checks 
as well. By increasing the refcount of the clusters affected and 
therefore enforcing COW, the collision is basically fixed as well 
without requiring this new function.

Thus I'm not sure whether this new function is actually necessary since 
the existing refcount check seems to cover all its functionality already.

But, well, I thought it couldn't hurt proposing this function at least. ;-)


Kind regards,

Max
