<div style="">Obviously, Dictionary>>associationsDo:
isn't really a leaf method. I suspect that Cog is generating
native code for the contents of the loop and it's not
getting interrupted by the tally process. (I've tried
running on an interpreter VM, but it fails with FFI errors,
so no help there.)</div>
