get_random_bytes() is not a _pseudo_ random number generator,
it doesn't have a seed and you cannot get repeatable sequences
out of it.

random32.c is though, but currently it's not reseedable either.
I needed a true reseedable prng a few times too so this
would be useful, although i guess random32.c could have been
fixed. But perhaps there's a need for a more cryptographically
strong PRNG too.
