    Two things to note. 1. It does for the standard system configuration which is
    1024 fd's so only a custom tuned box is vulnerable, and 2 the fix is vulnerable
    to deadlocks. Swap the kmalloc/kfree for vmalloc/vfree as I did when I fixed
    this in 2.1 a while ago and all will be well
    
    
    And yes - its a real bug. I'll try and see its officially buried for all cases
    in 2.0.33
