[PD] gop / tcl-tk cpu overload

maybe I didn't explained well:
the array is visible, but it gets loaded once and remains so (dimensions
200x90, not big). the reading point is made by a hslider which is behind the
array, so that should be quite cheap in fact.
it also happens that sometimes when I have more than one array the sound
gets distorted and remains so when I quit the patch (and load the standard
audio-test patch, for example). the behaviour is in general a bit erratic, I
can't also determine exactly when it will go wrong or not. but I'm sure that
it didn't happened like that before, so I don't know if I have the wrong
version of tcl-tk or something.
for example I made some time ago a graphical oscilator which also works as a
gop, which was a (bigger) array being continuously actualized (one can
define how often), and it worked with no problems.
something that I also don't understand is why the gop takes the double of
the necessary and defined horizontal space.
I send attached a copy of the pestering patch, I think it is small enough.
load the spieler-4, sa-sp is the abstraction.
