Within limits, using object introspection, this approach can be adapted so 
that it can be “applied once and works everywhere”.  See also my addendum.

It would be good if you published your findings in advance.

I do not see why it would be necessary to compare the number of calls around 
the world.  However, I cannot advise on hypothetical scenarios if I do not 
know all relevant facts.

There are console.profile() and console.profileEnd() (described on the 
Firebug website).  As for “real time”, you will probably have to find 
another way.  I would have expected console.profileEnd() to return the 
results as an object.

Yes, but how can I get the *call count* that way?
