Because .global_var is very much dark magic as far as users are
concerned.  If users are going to mess with .global_var, they'd better
know exactly what they're doing.  And if they know exactly what they're
doing, we want them to be able to tweak it all.

So, I think there should be two --params, one for the number_of_calls
threshold.  Another one for the number_of_clobbered_vars threshold (see
the end of find_referenced_vars).
