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.
