The idea looks great. The problem is just that you are using new / delete to allocate memory for the deleter. But the idea of using an allocator is exactly to avoid new / delete.

Moreover, in the case of the GenericGeometries, performance is of the utmost importance. Therefore, the solution should not involve an unnecessary function call just to avoid the use of a different interface. If we want to replace the PolyAllocator solution by an STL allocator solution, the latter one may not have _any_ impact on the performance. I am not trying to say there is no such solution, I just don't see it. Somehow, the STL allocators seem rather limited to me.
