-// randpool.cpp - written and placed in the public domain by Wei Dai
-// RandomPool used to follow the design of randpool in PGP 2.6.x,
-// but as of version 5.5 it has been redesigned to reduce the risk
-// of reusing random numbers after state rollback (which may occur
-// when running in a virtual machine like VMware).
