we could make this slightly more type-safe by leaving source abstract, and having a new_source (perhaps named for debugging) that generates the integer internally.

Oh, but that's what I meant by "no other meaning" -- source is really just used for mixing. It has zero meaning here, apart from being an integer.
This is basically its semantics.

.... and here how it's used. The idea is to exploit indeterminate ordering of provider's firing for a little more unpredictability.

As per discussion with @avsm .
Since the idea of
ENTROPYis not to provide random numbers, but environmental noise, and since this noise is opportunistic and not predictably available, instead of giving entropy on demand, the device now emits entropy when it has some.Goes with the corresponding change to entropy providers.
