The completely broken system is fixable, usually trivially fixable, and
once fixed, will stay fixed.
Maybe we need three sources of randomness: Ordinary random, never
blocks, somewhat predictable. Cryptographically random, blocks during
boot up, unpredictable to adversaries. True random. Blocks
frequently. On some systems, with limited sources of randomness, may
block a lot. Truly unpredictable.
