BTW, I think we do need a GrowCurrentStackTo API, to avoid predicted

Iirc the default stack size is 2 or 4 kb not 1 gb. Where did you found the 
reference?

[taozle]

I found that the default stack size for 64-bit is 1gb, but i can't see any 
reason for such a large stack, can anyone help me find out the purpose for 
this?
