I think the PR is still not in a good shape. I pointed out the problematic
code sections.
Also please bear in mind that people will always try to review your code as
soon as possible. But sometimes people are just busy and it takes some time for
them to review a PR. In such a case, one simply has to be a little bit patient
with them.
