[IPython-dev] IPython inputhook, higher rate?

[Gustavo Goretkin]

I'm looking to investigate this but I'm confused about some important things

CPython calls the inputhook at 10Hz according to [1]. You can verify this
with [2], so my issue isn't related to SDL or pygame. It's just that the
callback gets called infrequently.

How then am I able to manipulate my matplotlib window and type more than 10
characters a second into the interpreter prompt? According to import
threading; threading.enumerate(), there are no threads aside from the
"_MainThread" and "HistorySavingThread", so I think some threads are being
setup and run from the gui libraries (like wx). I guess I do not understand
what is meant in [3].
