Reloading modules on a large scale is fairly fragile.  You can get fairly
heavy-handed and force the reload of modules written in Python by fiddling
with sys.modules, but you can't be sure you've eliminated all references to
old versions.  For example:

    >>> import string
    >>> replace = string.replace
    >>> reload(string)
    <module 'string' from '/Users/skip/local/lib/python2.3/string.pyc'>
    >>> replace == string.replace

If my interpretation of previous posts on this subject is correct, there is
no effective (cross-platform) way to properly unload and reload extension
modules, that is I don't believe dlclose("") necessarily disconnects
the .so file from the running interpreter so that a later dlopen("")
forces the dynamic linker to do its complete dance again.
