For the record, git bisect shows it has been introduced in

    poll: make timer polls lockfree

    Make sure we don't take a mutex in the normal code path of the timer
    poll.

On the other hand, the following one fixes this (i.e. the cpu usage, please
file a separate one for the deinterlacer problem as mentioned):

commit 50d566d9ade049f8e42bb52add7cf1b9cba505df

    poll: trigger rebuild setup in _new

    Failing to do so in the Windows case (implicitly triggered otherwise)
    would have a subsequent _wait return immediately leading to high CPU
    usage timeout loops.

    Fixes #640675.
