    Ok. Part of cleaning up the interface SAPI module<->PHP will
    be to make stuff like this more clear. There is no way to
    tell that there is some interaction going on between the
    primary_file handle passed to php_execute_script() and some
    obscure function in fopen_wrappers.c through an undocumented
    member in the request_info structure.

    The old_cwd stuff in main.c is intended to reset the cwd to
    the working directory which was active before we entered
    php_execute_script(). The first time the virtual cwd is set
    during sapi_startup() which is usually called by the main
    web-server setup function, so I don't see a problem there.

    About the thttpd API: The source code is the only available
    documentation.
