[pypy-issue] [issue1514] module behaviour incompatibility which makes eventlet fail

[Armin Rigo]

Armin Rigo <armin.rigo at gmail.com> added the comment:

A lot of things can subtly go wrong with this patch, because it creates a new
module as an instance of the base class "Module", which can lead to all sorts of
unexpected issues...  For instance, if you do "del sys.modules['sys']; import
sys" then you get a sys module that is not really a sys module, e.g. it would
never have the attribute 'exc_type'...  Unsure how to solve this.
