Oh, yeah, yuck.  Is the use of signal() inherent to its proper
operation or can we get rid of that?

Or, would it make sense to do some research into PRNGs and use
that as a basis instead of truerand.c?  Or, is there some 
worthwhile aspect of truerand.c that merits our use of it?

I know that Knuth Vol. 2 has a bunch of stuff on PRNGs in concept.
I don't know how current that is.  Numerical Recipies in C has a
chapter on randomness (Chapter 7).


Does anyone have any other C implementations (under a suitable 
license) that would be good to use?  I'm not sure how good a PRNG 
we need.  I'm betting there are some piss-poor /dev/random 
implementations out there anyway.  -- justin
