    IPython normally runs kernels in seperate processes, but this setup is
    limiting in the case of QGIS because external kernels cannot access the
    data and variables that QGIS is working with. This class manages an
    in-process kernel and is capable of launching external consoles that can
    attach to the kernel.

    IPython Consoles are run as external processes because they rely on
    Version 2 of the PyQt api and QGIS is using Version 1 which is
    incompatible.
