Fix a profile sampling race.

Fix a profile sampling race that was due to preparing to sample, yet doing nothing to assure that the context remains valid until the stats are updated. These regressions were caused by 602c8e0971 (Implement per thread heap profiling.), which did not make it into any releases prior to these fixes.
