Andy made an interesting suggestion to me. What if the profile event
code allocated all the counters to the requested event. It could
reallocate half of them if a second event was also requested, and so on,
till we're down to one (unreliably interrupting) counter. Or we could
set a limit requiring at least three counters per event.
The problem would still exist, but this should throw the maximum amount
of ammunition we have towards minimizing it. Would this be worth the
effort to implement?
