SSLConnection Creation/Shutdown Procedure in M2Crypto

Hello!

I'm having some stability issues when using multiple SSLConnections. I
don't think that I'm using the object entirely correctly, particularly
during shut down. I've been learning this stuff from the demo files
included and there are some scenarios which they don't cover. What I'm
really after is an _explanation_ of the proper creation, transfer and
most importantly closing procedure for SSLConnection objects. I'll
whip it up into a proper Howto guide once I've got everything sussed.

((In particular, I'd like to know the specifics of when to use
close/clear/shutdown and how much data to recv(), but I'd very much
appreciate a complete start-to-finish overview, if anybody is up to
it.))

Thanks ever so much!
