Thanks for the answer.
Looking in the code, I found a 'user_ns' parameter in the IPShellEmbed
__init__() method. I tried to use it to set my context, and it seems to
work. The difference is that objects registered in that 'user_ns' context
are not seen whith the 'who' command, but are available.
What is exactly the purpose of this parameter? May I use it for what I want
