 Sure, but it's all the code between the function call and hitting
sys.modules which would also need to get shoved into the C code. As I said,
I have not tried to optimize anything yet (and unfortunately a lot of the
upfront costs are over stupid things like checking if  __import__ is being
called with a string for the module name).
