Comment (by bgamari):
In general your code will perform pretty poorly with or without
worker/wrapper if you have >100 arguments as this is well beyond what we
can accommodate in physical registers. Of course, I'm happy to be proven
wrong: do you have a concrete example of a program with this many
arguments which you think should optimize well?
