    Goodie. Are there other known problems with silly copy-protection
    schemes? It migth be worth testing.

    However:

    Yes. It seems I broke "strace" with it. Probably the difference in system
    call trace reporting that Dan Jacobowitz already pointed out.

    Now, that should be easily handled by just separating out the cases of
    system call tracing and debug trap handling, and using the old silly code
    for system calls. I'd prefer a cleaner approach, but that seems to be the
    sane thing to do for now.
