import imp

def get_module(name):
    (file, p, desc) = imp.find_module(name)
    m = imp.new_module(name)
    exec file in m.__dict__
    return m


_n_reloads = 0
def old_get_module(name):
    _n_reloads += 1
    suffix = "_reloaded_%d_times" % self._n_reloads
    # Yes, we're polluting sys.modules with '..._reloaded_n_times' modules
    return imp.load_module(name + suffix, *imp.find_module(name))

Idea: hook into exec'd file's import mechanism using the __dict__? To prevent the file from pulling in new modules (make them import using this).

Now we're basically getting into reimplementing the import mechanism :/
