    Ok I may have got the name wrong :). What I am trying to do is to
    implement a package on linux similiar to the TreadMarks by Alan Cox et
    al. (ref. http://citeseer.ist.psu.edu/amza96treadmarks.html) that runs
    at kernel level instead of user level. Right now I think that inorder to
    achieve what I want to do, I have to change the code of the linux
    virtual memory manager. This is ok for academic purposes (which is my
    aim) however it severly reduces portability (it is much easier to just
    load a kernel module than to patch and recompile the kernel).

    Thanks
    Josef
