Thiago, could you elaborate on this?

What does "moveToThread (this)" do that is different than (or more
pernicious than) "moveToThread (someThreadOtherThanThis)"?

What more does it do than I probably think?

I thought I had a good understanding of the Qt threading model,
but according to my understanding, "moveToThread (this)" is
technically legitimate.  (Whether it's good design or Qt-idiomatic
would be a separate discussion.)  So, given your comments, I'm
now concerned that my understanding is incorrect.

Thanks for any additional explanation.
