    But isnt this file counting a small problem ?

    This small program can eat all available memory.

    Fixing the 'file count' wont fix the real problem : Batch freeing is good but
    should be limited so that not more than *billions* of file struct are queued
    for deletion.

    Dont take me wrong : I really *need* the file RCU stuff added in 2.6.14.

    I believe we can find a solution, even if it might delay 2.6.14 because Linus
    would have to release a rc5
