py-gevent: updated to 1.3.4

1.3.4:
Be more careful about issuing MonkeyPatchWarning for ssl imports. Now, we only \ 
issue it if we detect the one specific condition that is known to lead to \ 
RecursionError. This may produce false negatives, but should reduce or eliminate \ 
false positives.
Based on measurements and discussion in issue 1233, adjust the way gevent.pywsgi \ 
generates HTTP chunks. This is intended to reduce network overhead, especially \ 
for smaller chunk sizes.
Additional slight performance improvements in gevent.pywsgi.

1.3.3:
gevent.sleep() updates the loop’s notion of the current time before sleeping \ 
so that sleep duration corresponds more closely to elapsed (wall clock) time. \ 
gevent.Timeout does the same.
Fix an UnboundLocalError in SSL servers when wrapping a socket throws an error.

1.3.2.post0:
Fix a packaging error in manylinux binary wheels that prevented some imports \ 
from working.

1.3.2:
Allow weak refeneces to gevent.queue.Queue.

1.3.1:
Allow weak references to gevent.event.Event.
Fix embedded uses of gevent.Greenlet.spawn(), especially under uwsgi.
Fix gevent.os.nb_write() and gevent.os.nb_read() not always closing the IO event \ 
they opened in the event of an exception. This would be a problem especially for \ 
libuv.

1.3.0:
Python 3.7 passes the automated memory leak checks.
Update autoconf’s config.guess and config.sub to the latest versions for \ 
c-ares and libev.
gevent.local.local subclasses that mix-in ABCs can be instantiated.
