And to answer myself (or post an answer i got from someone else, anyway):

"Any signal you don't discard will wake up sleep"

Which follows what I was seeing, it also explains why other code i've tried would work (or seem to, for the most part). Like:

for(1..15) {sleep(1)}

because every time an individual sleep would be interrupted it would just iterate through and try again.

If there is another explanation, let me know, but this correlates with everything i've seen and definitely gives me a way to move forward.
