Since Windows APIs use the Windows system heap, we should ask it to decommit pages in response to a memory-pressure event, similarly to what we do for jemalloc.
Starting with Windows 8.1, we can call HeapSetInformation with the HeapOptimizeResources information class to do this.

This would be very helpful. Last time I investigated Windows crashes quite a few had a significant amount of committed memory that was not used. This could help cut down on those.
