Silly import question (__file__ attribute)

[mh]

So on most modules I import, I can access the .__file__ attribute to
find the implementation. ie:'/data1/virtualpython/lib/python2.3/socket.pyc'

This doesn't work on the "thread" module:Traceback (most recent call last):
File "<stdin>", line 1, in ?
AttributeError: 'module' object has no attribute '__file__'

A few questions. Why? Where is thread.py or thread.so? (I can't find
it).

thanks

threadmodule.c threadmodule.o

It is a built-in module so it doesn't have a .so (dll) or .py file
to mention.

Wouldn't it make sense for module.__file__ to be set to None rather than
completely missing in this case?
