// Keeping the core of "runTest" as a separate function (as "runTestInternal")

// the function, when "runTestInternal" finishes its execution, they can all be
// freed, UNLESS something else is leaking them (and that's why we can detect
// the leak!).
//
// If we had all the code in a single function, we should manually nullify all
// references to verify if there is a leak, which is not maintainable and error
// prone. That's why "runTestInternal" CANNOT be inlined inside "runTest".
