// This code is part of the XPCOM extensions for Python.
//
// Written May 2000 by Mark Hammond.
//
// Based heavily on the Python COM support, which is
// (c) Mark Hammond and Greg Stein.
//
// (c) 2000, ActiveState corp.
// Unfortunately, we can not use an XPConnect object for
// the nsiModule and nsiComponentLoader interfaces.
// As XPCOM shuts down, it shuts down the interface manager before
// it releases all the modules. This is a bit of a problem for
// us, as it means we can't get runtime info on the interface at shutdown time.
