Arf bad news :/
Thx for your quick reply.
What's strange is that in "class IPShellEmbed" in Shell.py line 178 the same
trick like I did is used. So either, IPShellEmbed could be buggy either
there is a trick used inside that permits to restore sys.display hook...
Will read this code tonight, there must be a trick if you said that
sys.displayhook is important!
(in comment it  is said it used by 'exec' but so far I haven't seen side
effect, perhaps that's because I'm using a recent python interpreter...)
Will check result_display/outputcache too... thx

Cheers,
Laurent
