Comment (by DonMoir):

 Knowing where the problem is and getting in the optimal fix are a couple
 different things. I was hoping for more input on mailing list but only
 minimal response. I can kind of understand that since most do not use
 multi-video and multi-threaded in combination.

 If there is a consensus on locking the mentioned code statement then the
 fix is very easy.

 If there is not a consensus then we are back to square one wondering what
 the best fix is.
