After talking with Simon & Simon today, we discussed ticky profiling, and
it dawned on us that ticky probably isn't reported when the program is
interrupted via the user.
But it should be! The motivating case is when you're dealing with an
infinite loop and you want to find the binding that has a high entry count
(i.e. it's the looping body). But the only way to move forward is to
interrupt it, which doesn't spit out the reports. Fixing this would make
ticky much more useful in such cases.
