eventlet breaks select.poll()

[IamFive]

Hi, i try to install openstack ironic on ubuntu 18.04. And eventlet lib seems breaking things. But it's wierd that others do not have this issue.

I can simply reproduce it by:

Python 3.6.9 (default, Nov  7 2019, 10:44:02) 
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import eventlet
>>> 
>>> eventlet.patcher.monkey_patch()
>>> import select
>>> select.poll
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'select' has no attribute 'poll'
>>> eventlet.version_info
(0, 25, 0)
>>>

This is intentional, see f63165c. The client code is expected to check if select.poll (or other method) exists and fall back to select.select (or use the selectors module that does that behind the scenes).

thanks for the answer. will check why select.poll is called directly then.
