Changelog:
===========
- Make gevent.ssl stop reusing exception instances, as this could appear to
cause a memory leak if there are many short reads or writes.
- Fix Greenlet.dead returning true for an active greenlet during early
bootstrap.
- Fix some potential GIL-related crashes during interpreter shutdown by
avoiding acquiring the GIL in libev callbacks when the interpreter is
finalizing.
- Support for Python 3.9 has been removed.
