    It's not a requirement for users. The current implementation in the
    kernel it's just broken, ugly code.

    I have no objections against the userspace provided candidate list
    option, but as long as the main sources of trouble

    - invocation
    - reentrancy
    - timed, counted, blah ugly protection
    - selection problem

    are not fixed properly, we don't need to discuss the inclusion of a
    userspace provided candidate list.

    Postpone this until the main problem is fixed. There is a proper
    confirmed fix for this available. It was posted more than once.

    Merging a fix which helps only 0,001 % of the users to hide the mess
    instead of fixing the real problem is a real interesting engineering
    aproach.

    I don't deny, that after the source of trouble is fixed it is worth to
    think about the merging of this addon to allow interested users to
    define the culprits instead of relying on an always imperfect selection
    algorithm.
