Bug with threads in batch mode

[den1703]

P.s. check pull request

1. Load BIN/CUE
2. Press Start
3. Infinitive "Queued" and at the same time, you can see and hear the load on the computer.
   The resulting PBP file weighs 0 KB.
4. I click on “STOP” and the message “Abort processing?” appears, I select “Yes” and this window simply closes, the process does not end.
   The PBP file is still 0 KB.
5. I close the program and the PBP file begins to weigh 5/10/50 GB (The longer the process takes, the larger the file size)

Last working batch mode version is commit 2bd98f3
Other newer commits have this bug.
(Two bugs: STOP doesn't work + something wrong with final PBP file and with threads)
