pull up/down on pin 30/31

I know I could test this, but I thought it may be faster to ask.
Could it ever be a problem to have pin 30 or 31 with a pull up or pull down resistor on it? Like a 5K or 10K-ohm?
EDIT: that is, I concerned about it while programming the chip.

I am trying to connect other components to these pins, but I need some pull resistors (I should be able to arrange my hardware/software so it could accept up or down). During programming does the prop plug drive the pins high and low or is it set to input at some point? Or how does this work?
I also want the pins to be compatible with the propeller loader object.

I definitely recommend 4.7K pullups on both pins.
