I got problem with that even when crytographically secure
randomness wasn't needed more than once. A specific case included
adding jitter on some timeout to avoid all hosts to expire at the
same time, and used mersenne twister with a pseudo random seed.
There still were way too many hosts ending up with the same
timeout.
System time is not enough.
