@lantiga one of the leaks is solved, but we're still not freeing the tensors from the local context:

@lantiga the commit 9e060bb addresses the previous leak and adds the tests to it.
Can you check it?
It also adds AI_dictType AI_dictTypeTensorVals with proper valDestructor so that we don't forget to free values on dicts.
