fixes the issue. Thank you very much - although I feel a bit disappointed
about the wording used in the commit description. This was not a "super
rare edge case", it was a typical workload with many transcodes on
multiple gpus. Original commit (which is now reverted) mentioned for a
"blew up" which was never experienced. Original commit only made the code
keep unregistering and registering on every processes frame. So I would
expect a "sorry, we screwed up the code originally, so we are reverting
now" and not trying to tell that this was a "super rare edge case".
