    There is an issue of event notification.  It sure would be nice if we 
    had it.

    What if we added a third argument... a file descriptor that the kernel
    writes an exit record to.  -1 could be specified if the feature is not

    #include <unistd.h>

    __sys_set_exit_feature(int *addr, int data, int fd);

    Upon exit the specified data is written to the specified user address and
    a sys_exit_record structure is written to the specified descriptor.
    Both features are optional.  addr may be specified as NULL and/or fd may
    be specified as -1.
