>> Windows platform was checking the option against the current thread's stack size, and not checking ThreadStackSize, and was setting the stack size against that.  It worked until you increase StackShadowPages, and then the calculation is wrong.
>> For Windows, the minimum thread stack size with current StackShadowPages of 9 in debug is now 92K rather than 188K.
>> The ShadowPageSize is too low for the loom repository and is on the bounds of current mainline, so will be increased when Loom is integrated.  When increased to 11 StackShadowPages, the smallest stack size is 100K.
