    No. This thing is above the userspace interface and completely
    independent. Either a task is allowed, and then the request goes
    through to the interface. Or if it's not, the request is stopped
    right there, and never reaches the userspace interface.

    True. I'll send a patch (they are documented in the README of the
    fuse distribution).

    I leave the decision to you ;) It's a separate independent patch
    already (fuse-nfs-export.patch).

    Will follow up in Franks answer.

    Here's a description of a theoretical DoS scenario:
