Remove #ifdef MAP_INHERIT_ZERO. This is essential for fork-safety, so don't merely #warn about it. Attaining fork-safety without it requires restructuring things -- in particular, there's no clear way to make it per-thread and fork-safe without some global list of states to zero on fork.

Explain the security model in the man page. No more RC4! -- Grammar. -- Note relation of arc4random(3) to rand(3)/random(3). -- Ruminate on security model choices and API design in arc4random(3). -- Amplify comment about how quickly RC4 was known to be bad. -- Markup for BUGS note about arc4random_uniform. -- Cross-reference rnd(4). -- Remove unnecessary Ns before punctuation. Fix a line. -- Fix Google Groups link. -- Tweak wording, define `output', remove misplaced scaremongering. -- Fix non _REENTRANT build. -- Use ChaCha20 here as advertised, not ChaCha8. Oops. Fortunately, there is no public cryptanalysis even of ChaCha8: the best published attack is on ChaCha7 with time complexity 2^248.

I'm fairly sure the libc rules require that arc4random_addrandom, arc4random_buf, arc4random_stir and arc4random_uniform be weak.

arc4 is a random number sequence, there is no point using its own output values to determine a number of output values to skip. Skipping values on any possibly random event might be worth while, as might using the keying algorithm to stir in a possibly random value.

Since 'rs' is statically initialised (not bss) its s[] might as well be compile-time initialised as well. arc4_init) is the same as arc4_stir(). Initialise rs.i to 0xff (not 0) so that the first key byte is processed with rs.i == 0 without the splurios rs.i-- in arc4_addrandom(). Remove the assignment rs.j = rs.i at the end of arc4_addrandom(), it isn't necessary and I can see no justificationm for it. Replace RSIZE with __arraycount(as->s), however it is manifestly 256 (more correctly the number of values in rs.i and rs.j).
