It seems right.

paho python is a library.  Did you write code to use the library?

Can you point to where in the docs this should be explained and what you
found there?

Not having a clue, I would expect that when the process exits, the
pending messages are lost.  I would also perhaps expect some largish
limit on buffered messages, which when exceeed perhaps results in
dropping old ones, and perhaps results in an error.

I would suggest reading the source code.
