    I'm afraid I really need to do all the code, since I want to use it for
    a program which needs to set breakpoints at the functions I'm trying to
    get the addresses for. I looked at the gdb sources to see if I could get
    a sense of how gdb extracts the data, but couldn't get the hang of it.

    Another option would be to use /proc, but that's evil..
