ssl.py will raise None in certain conditions

[denik]

I haven't found a solid repro for this, but I get it from time to time when using an TLS/SSL enabled StreamServer.

Traceback (most recent call last):
File "/Users/<snip>/init.py", line 263, in handle
num_read = sock.recv_into(buffer, BUFFER_SIZE)
File "/Library/Python/2.7/site-packages/gevent/ssl.py", line 256, in recv_into
raise
TypeError: exceptions must be old-style classes or derived from BaseException, not NoneType

I'm guessing the reason is that the re-raise is done after sys.exc_clear() in ssl.py:
http://code.google.com/p/gevent/source/browse/gevent/ssl.py#268

What version of the gevent are you using?
0.13.7

On what operating system?
OSX 10.7.3

On what Python?
2.7.1

Please provide any additional information below.

Indeed, we should not do exc_clear() before raise.
