Be aware that heavy twisting of the bars to free a stuck stem, while holding the wheel from turning, can neatly break one or both of the fork's axle-slot "dropout" tab ends, or worse, you could get cracks down there which might lead to failure while riding.
Yes, I've seen a dropout get broken off this way, more than once.
