+               timeout_hz = (timeout.tv_sec * hz)
+                          + ((timeout.tv_nsec * hz) / 1000000000);

It looks like we might have the chance of an overflow here.
hz * 999,999,999 will be > 32bits for pretty much any value of hz.
Maybe look at hzto() in kern_clock.c to see how it avoids
overflow?
