While doing the network emulator, I discovered that the default net_random()

another function in just for sch_netem, how about making net_random() smarter?
The tin-hat crowd already replace net_random() with get_random_bytes anyway.
Here is a proposed alternative to use a longer period PRNG for net_random().
The choice of TT800 was because it was freely available, had a long period,
was fast and relatively small footprint. The existing net_random() was not
really thread safe, but was immune to thread corruption.
Is it really worth the extra spin lock & math? Maybe we could have a
net_more_random() method instead that encompasses this improved random logic?
