Yes, when the IPython kernel is *executing user code* the wx event
loop is blocked.  But otherwise the kernel is just sitting there,
waiting for events to arrive over the network.  Simply try running the


in the docs/examples/lib directory and play with it.  A little bit of
interactive experimentation should clarify things.  Let us know if
that's not enough.
