    If all architectures would finally get a vdso implementation you could
    just add the necessary stub in the vdso, add a symbol in the symbol
    table of the vdso, and use in the userlevel code

    sym = dlsym (RTLD_DEFAULT, "the_symbol_name")

    If the returned value is not NULL the symbol exists.

    I've described this many times as one of the huge advantages of vdsos,
    hopefully this time it clicks.
