entropy estimation, but causes an immediate reseed after the input (read in sizeof(u_int64_t) chunks) is "harvested". This will be used in the reboot "reseeder", coming in another commit. This can be used very effectively at any time you think your randomness is compromised; something like # (ps -gauxwww; netstat -an; dmesg; vmstat -c10 1) > /dev/random will give the attacker something to think about.
