Indeed.  I believe something very similar to this code
is what let those guys in Berkeley break the 40-bit
SSL from Netscape a while back...

Try something better. Like, maybe:

 strand( time(NULL) | getpid() | getppid () );

It's too easy to predict a purely time based password generator. Even adding
your process ID and parent isn't really a good enough protection from a snooper
on the same machine.
