Not sure what you are trying to tell me with attached PHP code.
I hope my script is understandable to those who embedded IPython into
their own python application.
Some details, that I forgot to mention:
I'm using IPython 2.0 (the API is different to the predecessor versions)
and I based my code on the examples shown on the IPython web site.
However the example code doesn't seem to work in any other thread than
the main thread.
Related link:
http://ipython.org/ipython-doc/2/interactive/reference.html#embedding
thanks again for any help.
I'm rather curious to learn why the embedded kernel seems to block and
top find a way to circumvent this behavoiur.
