    ??? I am fixing nothing. The old code is not buggy.

    The changes doesn't impact at all the fast path. It will only decrease the
    irq latency during contection with the only cost of running _a_ cli before
    trylock _only_ each time we exit from the slow path.

    Anyway I don't care. It's a 5 minutes hack and I just had my fun in
    playing with it ;).
