    Original change's description:
    > [cpu-profiler] Fix a bug which caused a pure virtual function call
    >
    > We need to remove each Sampler from the SamplerManager before we call
    > the Sampler destructor. This is because the signal handler can interrupt
    > the destructor, and call DoSampler(), which calls sampler->SampleStack()
    > on the sampler being destructed, causing general unhappiness and
    > "Pure virtual function called!" crashes.
