Description Kim van der Riet 2014-01-16 20:51:44 UTC 
The use of /dev/urandom for random numbers is considered unfriendly to other systems on a machine that might depend upon this source.

The current use-case is for Journal serial numbers; the randomness of the C rand() call should be good enough, but it requires a 64-bit number. Construct this using several smaller numbers from rand() or random().
