It's true. At least until someone proves me wrong and submits a working
patch.

I have blissfully forgotten the finer details of imp.load_module() but
you can fake an import with code like this. It creates a module, inserts
it in sys.modules and execute some code in the module namespace.

moduletext = """

import sys
def foo():
    print sys.path

"""

import sys, new

sys.modules['mymodule'] = mod = new.module("mymodule")
exec moduletext in mod.__dict__
