Semantic "Sticky" in python mode

I would like to know how to disable or - preferably - fix semantic when in
python-mode.

It generally works okay; I know the engine is running in the background -
even though I have no means to use autocomplete as it never finds the
symbols (but perhaps completion is best left until later. For now it is not
relevant to this thread).

I noticed today when I was running through a large python test source file
when I put the cursor anywhere in this function emacs freezes/is sticky for
2/3 seconds. It is very annoying and it only seems to happen in this large
function.

I have tried running putting this in my .emacs file:

(remove-hook *) for all functions called on python mode - confirmed by
viewing the value of the variable python-hook - just like suggested by Eric
in: http://sourceforge.net/p/cedet/mailman/message/25629503/.

However, this does not work. Even if those functions are not called when a
python file loads semantic kicks in.

So, 

1. how to disable semantic for all python files? Something better than
running (semantic-mode) [[ which does not work anyway ]]. 

2. OR, how to fix the issue where emacs sticks for 2/3 seconds when I move
the cursor to a large function. 

3. And, as a bonus - where to find information about what I can use a
frontend equivalent to what I do for c++ with ia-complete-symbol-menu.

Cheers.
