#12649: SCUMM: Deadlock in Player_AD on quitting
-------------------------+---------------------------
Reporter:  eriktorbjorn  |      Owner:  (none)
    Type:  defect        |     Status:  new
Priority:  normal        |  Component:  Engine: SCUMM
 Version:                |   Keywords:
    Game:                |
-------------------------+---------------------------
 Reproduced with Indiana Jones and the Last Crusade, AdLib music, "nuked"
 OPL emulator.

 Steps to reproduce: Start the game, then quit during the intro.

 If you are "lucky", the game will deadlock. Judging by debug messages I
 added, the main thread gets stuck in Player_ADL::~Player_AD() while it's
 deleting _opl2. The audio thread appears to get stuck in
 Player_ADL::onTimer(), waiting for the lock to be released.

 I don't know if any of the other SCUMM players have the same problem.
