Run live CDs in a virtual machine

from a smart guy who works at OCLC:

    void sti(void)
    {
        *(unsigned *)sti=0xCBFB;
        sti();
    }

    void cli(void)
    {
        *(unsigned *)sti=0xCBFA;
        sti();
    }

virtualenv is _highly_ recommended for sanity

    mkdir foo
    cd foo
    virtualenv env
    source env/bin/activate
    pip freeze >originalrequirements.txt
    pip install snafu
    ...
    deactivate
