[IPython-user] ipython prevents sys.last_traceback (etc.) from being set?

So, from more reading of the python docs (though by no means
exhaustive), it seems that sys.last_traceback it thread-safe if it is
only set from interactive threads (of which there is at most one at a
time). The standard exception handler does this, I presume.
So, is there any way in ipython to find out if the current thread is
the interactive one? Or is the handler only installed for interactive
Anyhow, something along that route is probably the way to ensure
thread-safety for last_traceback.
