[IPython-user] Closing an embedded IPython Shell.

[Brian Granger]

Whew, this is much more complicated then.  A few comments:

* Is your GUI running in the main thread?  Most GUI toolkits I know of get
very grumpy if they are not run in the main thread.  This alone could cause
problems.

* Are you uses IPython's threaded shells to integrate ipython with the GUI?
If not, can you better describe how the two are integrated.

* Sometime very soon (like next week) we will be merging some new code into
the ipython trunk that will have a much better way of doing GUI integration
(it doesn't require threads).  While I haven't tested it with embedding, it
should make these things much simpler.  Note:  this new stuff won't be in
the upcoming 0.10 release.

Cheers,

Brian
