Why do you think some interpreter ID (if such a thing did exist) would be fundamentally better from a randomness/predictability perspective than time+rand, or something similar?

Do you actually need cryptographically secure randomness, or simply distinctness (as one might have inferred from your OP)? A simple counter (like a sequence in a DB) would be producing distinct values, although they're essentially 100% predictable. And as time is like a counter - automatically incremented externally of your program - it doesn't seem like a bad choice in case distinctness is all that you need (and if you're worried about being returned the same microsecond, just wait until it has advanced...)
