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
False
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("bsddb.so") necessarily disconnects
the .so file from the running interpreter so that a later dlopen("bsddb.so")
forces the dynamic linker to do its complete dance again.
