CC to get Guido's attention
First of all I don't understand what you mean with "that some imports
are inside the call() function". Please elaborate on it.
I skimmed through the code and found just a handful of modules that are
important by name as well as imported more than once through the life
time of a python process. The most noticeable modules are time,
_strptime, resource, unicodedata and warnings. The other modules like
__builtin__, zlib and warnings are just loaded once or twice during the
boot strapping of the interpreter.
Guido:
What do you think about storing the modules in an "extern PyObject
*PyMod_Spam" variable? I could either store them when they are used the
first time or I could load them in Py_InitializeEx.
