Looks fine. Thanks!

You could mix in some more get*id numbers.
If we really care, using gnulib's gethrxtime module
would be nice, but parts of it are GPL'd.
Here's part of coreutils' gl/lib/rand-isaac.c:
void
isaac_seed (struct isaac_state *s)
{
isaac_seed_start (s);
{ pid_t t = getpid (); ISAAC_SEED (s, t); }
{ pid_t t = getppid (); ISAAC_SEED (s, t); }
{ uid_t t = getuid (); ISAAC_SEED (s, t); }
{ gid_t t = getgid (); ISAAC_SEED (s, t); }
{
xtime_t t = gethrxtime ();
ISAAC_SEED (s, t);
}
isaac_seed_finish (s);
}
