especially, is DBResultSet cloneable?

or are all the methodmaps and handle cloneable?

All handles should be able to be cloned by the plugin owning them(as well as be able to change ownership of the cloned handle)

That seems not true

According to said wiki page, it is true what I said.

A plugin owning a handle can clone it and be owner of new clone or explicitly provide the new owner of the clone

Usually Handles are Cloneable and Closeable unless otherwise documented.

Having said that, cloning DBResultSet strikes me as an extremely bad idea. CloneHandle makes a second copy of the Handle¹, not the data.

Why is this important?

Because calling FetchMoreResults or Rewind affects the data. If you call it from either Handle, the data available to both Handles changes.

¹This uses reference counting, meaning that the object referenced by the Handles isn't deleted until all Handles to it are closed.
