I was wrong about eventlet - it does clean up exc_info. It never restores
it, so you get:

denis@ubuntu:~/test_greenlet$ cat eventlet_test.py
import eventlet
try:
    1/0
except:
    eventlet.sleep()
    raise

denis@ubuntu:~/test_greenlet$ bin/python eventlet_test.py
Traceback (most recent call last):
  File "eventlet_test.py", line 7, in <module>
    raise
TypeError: exceptions must be old-style classes or derived from
BaseException, not NoneType
