Indeed, and that's PAPI's strong point.
We could try to utilize it via some clever LD_PRELOAD trickery?
Adding a testcase for every bug that can be triggered via tooling
would definitely be an improvement as well - those kinds of testcases
generally tend to map out the really important bits faster than an
attempt at exhaustive testing.
