After debugging and debugging again, I found that I did SSL over SSL ... 
And in this case I was not able to shutdown the second SSL connection.

Now that my code doesn't do SSL over SSL, I can corecly shutdown() and 
then close() the connection.

[OT] sad that shutdwn() doesn't take an argument like the standads 
socket. I know it's discussed in bug 900792:

Sorry for the noise!
