I profiled a shutdown that did late writes, but my "Late Writes" section in about:telemetry is empty: http://people.mozilla.com/~bgirard/cleopatra/#report=e2789c613c5c5f1a508ef8a6f0d7fb773b157c95
It is just that this write is not late enough. The write is from NS_XPCOM_SHUTDOWN_LOADERS_OBSERVER_ID and we poison writes about 30 lines after that in nsXPComInit.cpp.
