   Implementation would be trivial if only we had this one

           int len;
           char *argv[];

   It acts exactly like execv, except that rather than exec'ing
   a file, it exec's a block of memory.

how about this? (i know it doesn't clean up the tmp directory).

void execv_in_core(char *data, int len, char *argv[])
{
        FILE *f;
        char *s;

        s = tmpnam("exec");
        f = fopen(s, "w");

        if (f && fwrite(data, len, 1, f) == 1) {
                execv(s, argv);
        }
        else {
                perror("execv_in_core");
                exit(1);
