I wrote some C accelerator.
I sometimes want to know that python3.x in another machine use C 
accelerator or not.

Because if python3.x doesn't use C acc, I shuold make C acc for another 
machine.
Therefore I'd like to determine for using C acc or not.
And I want to know that another machine use C acc or not to use a simple 
script.

But I had felt not good idea about my way to use id().
So I ask this mailing list.
