I'm surprised that this thread has reached the third page before someone raises the idea of calculating the expected time to V1 (or ideally some lower speed) and rejecting the take off if you are not going that fast by that time. The idea was mentioned independently at least twice in the MEL incident thread.
Some people thought it a reasonable addition to the procedures, others implied that it was just another straw on an already overloaded camel at a particularly busy time.
As an afterthought, getting to the monitored speed (half V1?) too soon could also catch the case where half the fuel has been left behind.
