I might actually also rename the variable to indicate the base.

Sorry for the confusion here, but I just realized that the default stack size should already be 1MB... why are we ever setting this explicitly if the config option isn't set? We should confirm that the default is 1MB and just not set it unless the user specified something else.

Default for .net core is actually 1.5 mb.

and actually for x64 I believe it is 4 MB

Just checked... it seems like it's 1.5 MB for both 32 and 64 bit on Windows, for .NET console apps. However, I'm not sure that also applies in the IIS case. Will confirm that.

Looks like in IIS we might have smaller stacks. With that in mind, this change seems fine (and strictly better than it was before).

Do the checks need to be re-enqueued?

I am not sure about those 3 other checks but they seem to have failed again.
